First just a disclaimer... I’m not looking for any solutions to this problem because I have already tried everything. This is mostly just to vent and rant and maybe find some poor soul who is or has been in the same situation as I am now. I met her 4 years ago and we were pretty good friends up until now. Things changed whenever I started to date her brother and now things are at an all time low. It didn’t help that we both got engaged and married within a few months of each other. She had four wedding showers and I had to attend all of them out of friendship and future sister in law obligation. The three days before her wedding, me and a few others helped set everything up. The day before, I went and got my nails done with her and the wedding party, and stayed the night with her at a hotel, even though I did not know any of her wedding party and was super uncomfortable. Well, finally the time rolls around for my wedding, and what does she do? Absolutely nothing. Backed out of every last thing I had planned for my bridal party. Did not get her nails done with me, claiming to not be in town in time, but arrived the day before we were supposed to go. Then backed out of staying with us the night before at the hotel because she wanted to “see her family” even though she had been home the week before. That was only the least of things that have happened so far. She is also a one-upper and has to compete with everything I do or get. My husband and I went to Disney World for our honeymoon since he got his tax return money back a few months before our wedding, and my parents were able to buy our rooms at a resort for the week. Once she found that out, all she wanted to talk about was her big one year anniversary trip, which grew from Florida, to the Bahamas, to a cruise to the Virgin Islands. I’m sure the next thing she will probably add is a trip to the moon. I don’t even want to tell her that my husband and I have booked a cruise to the Bahamas for our one year anniversary because we got a really good deal on it through a friend, because no telling what she will do to top that. But I do take her with a grain of salt because most of the things she talks about never happens. The most recent thing that happened was when I bought a pair of AirPods and was using them when she and her husband came to visit. A week later, she was showing off her new ones on Instagram. It’s actually hilarious when I stop and think about it, but it’s getting really old. Anyone else have a SIL like this?
