My “mother-in-law” Hates Me…?

okay, long story short. i am 26 female, widowed, and now with a wonderful man. my husband’s parents absolutely adore me and they’ve insisted from day one that i call them mom and dad, and they even say “i love you” to me all the time. i am their daughter. but my boyfriend’s parents are So Not like my husband’s parents. my first day meeting them (a year ago), i happened to have my hair dyed pink and they saw my 2 tattoos on my arm.. they judged me as a no-good rebel right from there. his mother demanded we get a hotel room while i was visiting, because she didn’t want me in her house. my boyfriend still lives with them (he is saving for our house). since that visit, she has let me stay with them, but treats me like total crap. she scares me, because all she does is ***** and scream about Everything!! i’ve only seen her smile once, and that was because she had out-of-town family visiting for Thanksgiving. i try So hard to please this lady and make her like me, but it doesn’t work. i visited last week and i said “hi” to her in a very pleasant voice, and she said “hi” in the nastiest, meanest, witchiest voice ever. what am i supposed to do? kiss her butt? i know everyone will say “don’t worry about it”, but this lady will be my mother-in-law someday.. i am going to have to deal with her for the rest of my life! his dad is okay, but he only asks me how the weather is in my town. that’s about it. neither of them have Ever asked me or brought up my husband at all, and they have No interest in getting to know me, because this whole past year they have asked me 0 questions about my personal life. don’t they understand that i lost someone so close to me, im going bankrupt, and im dealing with college.. what makes them think i want MORE stress?!?!?!?
*ps* they are not the type you can sit down with and have a nice heart-to-heart with.. at all!!

i agree my boyfriend needs to give her a piece of his mind, but until he/we can afford to get our own place together, he has to put up with her. he feels if he pisses her off now, he may have to put up with her being even worse until he can move out, which may be 6 more months from now.. or longer.
