I’ve been trying to think rationally about this all day, but going around in circles. My SIL has been really difficult since before I even really knew her, and DH acknowledges her many batshit moves, and my other SIL is just plain off. Much of this comes from their parents who thinks only son is just the bees knees (I don’t think this btw), and I’ve got the fallout from their uneven ..affection? Every family get together is a nightmare, and yet again christmas planning has turned into a problem. My issue today is that I finally snapped. After 20 years, I actually emailed her what I thought, and, as she had written and cc’d in her parents, and the other sister, and their husbands, as well as mine, it went to them too. I immediately wrote again to apologise for being rude, but admitting it was the truth, but I was just so distressed I wasn’t thinking clearly enough to keep it to myself. DH and I are having a tough time anyway, and we have many kid issues etc, we need to keep our sanity, but he is terrified that I’ve irretrievably damaged everything, and he is definitely of the “suck it up and pretend their not there” if they’re being awful. I know I have a DH problem, but at this moment, what would you do? More emails?, leave them to it?, wait for someone else to get in touch? I am so upset that she has been a miserable shadow over the last 20 years, and even more upset that now I’m the cow because I’ve been rude.
