Bil has been with his gf a few years now and she has always been very "shy". I have made a lot of effort to get to know her, involve her etc, to the point where we do now get on, but conversation is still an effort and sometimes I wonder why I bother trying to be sociable with her. However, have been recently wondering if she is not shy but more just deliberately antisocial manipulative, and she has turned previously fun loving Bil into a misery.
She and Bil are now engaged and her behavior seems weirder since then - you would think she would be on top of the world but she is miserable. She graduated this summer but has yet to even apply for a job. She is currently living in a flat owned by wealthy PILs who pay their bills, and will be funding their upcoming wedding. At new years eve party hosted by the Pils everyone else was dressed up but SiL said she wasn't feeling well and came down in jeans and slouchy grey hoody - it didn't look as if she had even brushed her hair and proceeded to eat very little and roll her eyes at midnight when everyone was singing Auld Lang Syne. I know she was not well, but I don't think it was an excuse for being rude. She seems to always want to bitch about other Bil and his fiance who is pg - when the fiance showed us her 20 week scan pic, she tossed it onto the coffee table and didn't say anything!
The thing is, PiLs seem to love her and are always making excuses for her behaviour - It makes me angry as she seems to want to love off them and I fel she is taking advantage, but don't think that saying anything will solve anything.
