A bit of background... I've been married into family X for a few years now, and naturally, some LTR's have developed with regards to my wife's sisters. In particular is one boyfriend, who I think has some good principles. I'll call him Bryan. He works hard, has a car etc. It's just that the (my) SIL, is. fucking. crazy. And she is absolutely going to work on this otherwise good enough guy, in advance of their certain marriage. She's technically "family", but I wouldn't recommend her to any guy I know. She is bat-shit crazy.

This is Bryan's first relationship, so he's ready to put a ring on it. She is way out of his league, which you would think is fine... But this has put her on a very high pedestel, where he doesn't even notice how he's being conditioned to accept her behaviour. She doesn't even have to do any shit tests, she just gets what she wants. His own brother endorses his approch too, which I find ridiculous. She gets full access to his email passwords, entire warddrobe, choice of job. The works. I assume they will be married when she decides. He'll get a share of her school debt ($100K), she gets the status symbol and the chance to be a permanent SAHM, with no intention of going to work. Just last month, she flat out admitted she was not attracted to Bryan. I told her how dishonest that was, and she almost went nuclear. She really and truely believes there is nothing wrong with what she's doing.

I wish I was making this up. It's entertaining to watch this from afar via social media, or at family gatherings, but honestly, I feel bad for the guy. I'm not sure if I should just let it go and see how things pan out... But this isn't going to end well. The family is thrilled for another wedding (and grandchildren) so they're really gungho about this happening.
