Thanks a lot for the replies, frankly I am more annoyed with my sil.. as I always had a friendly relation wid her and always treated equal to my sis .. i talk to her freely and share things as i do wid my sis .. she comments me indirectly but i always ignored them thinking I shud concetrate more on positive stuff.. I heard her commenting on my parents too sometimes.. but i tried to ignore it too.. but this one mesaage have been bothering me since i saw it..but as you all have suggeted i am trying to leave this issue for now.. hopefully i dont blurt out during some argument
Yeah, that's a tough spot and anyone would be annoyed and distrustful. All I can say is that again, it seems like she's preconditioned to think critically of your parents given that she's hearing a biased perspective from her own parents. Not totally sure what the best path is to remedy that other than giving her a proper chance to get to know them and off-setting her parents' opinions with those of your DH and you.
now that you are aware of what goes around behind your back, strategise and act accordingly that is act cool.
OP, ignore your SIL, i believe your DH just told something that she wanted to hear.. knowing very well by saying that he can end the conversation.. dont judge your DH so soon, give him the benefit of doubt. dont discuss this either because he may think you are spying on him. continue to be normal with your DH and well SIL doesnt count here.. take care.
Just to pick up fight she might have asked those, she very well knew that your husband maintains a distance still to trigger him she would have done it. When both of you are in good mood talk on cherishing moments as well as those hurting. At that time you ask him why he doesn't like or maintain a gap with your parents. Don't mention whatsapp and all. Just talk and clarify. So that even your bad feel would vanish.
