O dear..you seems to b very misunderstood by yr in-laws. Tis problem, I think only yr hubi can help. He can talk to them by himself, you dont b around?
I also go back every wkend to my mum's place but my fa-inlaw is very fine w/ it. Yr mother in law abit too much by saying that about yr parents ..can imagine yr anger. Mus ve been hell of a roller coaster ride of emotions for you..
Do you reali ve to live w them? How about getting yr own place?
