moneyminded MIL and SILs

Even after eight years of married life,still couldn manage my SILS and MIL.
for all my inlaws trips to attend functions,my husband has to take etickets.They go atleast 5 times a month saying one/the other function.my SILs will get money (thousands of rs)saying urgent need and never return back.MIL wants us to get costly dress for all of them yearly twice.whereas she'll get a saree worth 200 rs for me once in a yr.inlaws get pension even then they'll ask money from my husband every month.SILS (both'r married) whenever we go to inlaws home,my inlaws have a list of places to visit .so my husband 'll arrange that .the whole family'll (INCL.SIL'S FAMILY)come for each and every tours.my BIL (unmarried)will give nothing to his parents whereas he gets money both from my DH as well as his parents.my husband 'll get all costly toys,dresses for his sister's children ,but though the sils 'r well off,they'll get very cheap materials for my daughter.sometimes she'll give her son's used dresses too.i feel irritated on their behaviour.:bangif i ask anything,my DH 'll say it's his duty to lookafter his family members.I don say that he must not help his family members.
he must understand that he too has a daughter,without any savings what we'll do in future.i'm really worried.:help
