On the subject of in-laws, I guess they aren't really mine, but rather my son's. his mother-in-law is a walking psychosis. One minute she's an accomplished business woman, the next she's a raging psycho.
I have seen her say the worst things possible to her daughter, to the point where even I was in tears, to think someone could say such cruel things to their daughter - for no reason. She's jealous of the little time we spend with our grandkids and daughter in law and son, she's brutally cruel. She's manipulative, threatening things, demanding past gifts be given back, even demanding the shoes on her own grandson's feet, saying they're disowned, accusing my son of unthinkable things, threats to call CPS (even though there is NO reason). She berates her daughter and thinks we are the devil's spawn.
But then she's nice, like nothing happened, and thinks we should all have dinner together or plan a vacation. I can't stand to be in the same room with her, for how she has treated her beautiful daughter. But my DIL desperately wants a relationship with this nutjob, and that is her choice to make - though I've told her I think she'd be better off going to get counseling to figure out how to deal with her without feeding into her frenzies.
Unfortunately, this means our son and his wife have to divide their time between two families - but I'm just not willing or able to forgive or forget what I've seen this woman do to my DIL and my son, nor to a lesser extent I can't forget the things she has said about us in her jealous rages. My husband thinks she's crazy, but he's much nicer than me and would put up with her. I don't think I'll ever be ready to.
