Biased Husband

Dear friends,
Offlate i have been busy so come here seldom.Life has been fine with some mountains and some plains.
Those who dont know about me,let me make it short.I am married to the only son,who is manipulated completely by his widowed mom.He lost his dad when he was in college so they hv been quite close since then.I have a sis in law who is married in a diff country.I had lot of problems in the initial years of marriage but gradually learning to deal with them...though some of the things pinch me even now.
Its been close to a decade.My baby is 4.5 now...
Since the beginning mil has always made my husband distant from my folks...She never entertained him meeting them and being close to them.I had lots of fights for all stupid reasons ever ,whenever my folks came to visit ,since my mil always humilated them.My parents always came to help me and stayed with us ...it was either my deliver or 2 major surgeries i had gone through...that time was hell for me since i was physically and emotionally broken down and my mil used to always poison my husband for them
Past 4-5 years he has not visited my parents place even once...though i go and spend time with them and take my daughter also...they try to create problems for me for doing that but i put my foot down...I love my family v much and i am v close to them so i dnt want to be deprived of being with them.They know i will not listen to them.I just book the tickets and go.
Now coming to the point....we had a vacation for the first time to Sils place who lives abroad....
To my surprise,i saw her house so mismanaged....for whom Mil used to compare me all the time...Now i know what she is.My sil also has always kept a distance with me since beginning....we have a formal relationship.She has 2 kids...i have one...so when my child was born,she sent so many old clothes to me saying my child can wear them...i was furious...I told my mil in simple terms that i will not make my child wear all these...Most of them had turned yellow and looked so old...(We give gold to her everytime she comes and give the best of dresses to her kids still she finds faults in them).So this didnt stop here..
One year later when her husband visited our place she again sent me a pile of old clothes for my baby...I was like what the hell...cant i afford new clothes for my baby...The idea was that i should sort out from them and see whatever we like we can take from them since they are branded clothes.i had fights with my mil and my husband both... My husband happily took out few from them and made my child wear them...but i st away said that she will not wear these.okay may be 3-4 clothes may be good but why does she need to send the whole pile everytime...that was my hatred about ,why cant she just send few good one ,imagine she even sent few used bibs...does any one give used bibs to any one .Now this time when i went there she again had a pile ready for my daughter...every day she used to tell me to check which ones i want to take.I told my husb that dont wana look at that...but he has never supported me,neither infront of sil nor mil,i have to fight my own battles.I avoided saying i will see later ,then even told clearly that she has many new clothes her cupboards are full,she doesnt need them,but she was insistent every day still saying at least have a look.So one day to please his dear sister he took out the pile and started searching.I did not respond then told her v clearly saying if you 4-5 good special dresses you can give her and i will take them but i dont like sorting.She said all are special to me..So i sat up and spoke...''Dont mind but i felt v bad when u said so many old clothes to her,she was just born...many of the clothes had even turned yellow since her daughter is 4 yrs older than mine.i dnt want to look through all this ...if u really feel there are some good dresses u can take out urself i will take them(even i have worn my cousins as a kid,good dresses which were really nice,since kids grow fast and i understand that ,we dont feel like giving them to maids too since some are v nice dresses).But the point if she would even put casual clothes there which look like crap...i told her straight that u even sent clothes which we wear at home...She became so aggressive and went away in anger.Everyone dispersed and all were angry since i stood up.I cant tolerate nonsence.Now next morn i just said good morn and carried on...since we were at their place.We had to go shopping that day.So my mil went with me,my husband stayed with sil sicne both had some office work saying that they will join later.
And when my husband came to the mall he was furious(probably both bro and sister fought v badly ).So everything came up on me...He was saying we need to go home today...you spoilt my holiday...andthis and that...my mil joined him cursing me and my family.
My sil is basically v dominating being the elder one and has got what she wanted.My mil is always like a monster to me but infront of her she is a meek woman.Everyday my sil used to shout at my mil their for the household chores since she used to go to office and my mil had to handle her kitchen and babies..Mil in turn doesnt like helping anyone she has never helped me too...so she used to bitch about my sil infront of me and my husb everyday..So there was a drama everyday.
Now probably after my conversation with her she fought with my husband complaining about my mil too...
So here my husband doesnt see his sisters wrong nature.
i told him straight i will talk to her personally...and i did...In the eve calmly spoke to her that whatever differences we had, why should that spoil your and ur brothers relationship..a brother sisters bond is v diff.He loves you dearly and is v stressed with the fight.Why could you not clearly talk to me .I told her that i dont like the causal clothes being sent ,,,she could have simply taken the good ones out n given me...She understood i felt and the whole atmosphere became fine...My husband didnt speak to me for a day but later became nml seeing things were in place...
Later infact i took ONLY party wear dresses from her...just to make a good relation and clear the point.
I did it just to let the relationship go smooth and then we cam back finally....
Was i wrong here??can anyone suggest.Secondly my brother who lives altogether in a different country is coming to me after 2 months with his new born baby...so i bought few new dresses for her ..Mil gets so irritated whenevr i buy something nice for my family...Inturn they give me so many things...I overheard her telling my husband (When they were keeping the stuff which my sil had given)saying see such good desses they were and she created a scene.You do the same when his brother comes.
I feel really depressed and anxious fr these things...Inspite of me making the effort and sorting out stuff with his sister also still my mil has a habit of poisoning my husb for my family...
Now i want their stay to be happy sice its just a week...but i know my mil will do something or the other withmy husband.How to manage this...can anyone suggest.Sorry for the long post.
