So, you guys know all about the struggles I went through with my older daughter the past 4 or 5 years...she has borderline personality disorder and she's been in and out of temporary-stay juvenile psych wards over and over again. Fortunately though, she is scared enough of the adult facilities to actually take her medicine and stay pretty balanced out...she's ALMOST 100% normal on her meds. Another big thing that helped was her moving in with my wife's parents about 8 months ago; I just think she needed to get away from us since she has so much resentment in our home. There hasn't been any serious meltdowns since she left but then again, they don't challenge her on anything either. She doesn't clean up after herself, doesn't take care of her dog, doesn't have a job anymore, etc...so there's zero stress involved and nothing to stress out over. Plus, she's smoking weed (illegally) which mellows her out anyway. A big part of her doing better though is a guy that she's been dating- they were friends for a long time and she wasn't interested in him at all. But this guy was always there for her, always supportive, and he could often calm her down before she started to go ballistic when nobody else could. They finally started dating about four months ago, started sleeping together maybe 6 weeks ago and then a "promise ring" came immediately after that. The boyfriend is madly in love and will do everything he can for my daughter, plus he's a really good guy. I mean, he's spending 8+ hours on his days off doing chores around my wife's parents house...chopping wood, painting rooms, etc. He's 23ish, a meat cutter at a grocery store and seems pretty career-driven, so I'm not worried about him being there for her or supporting her. I mean, they'll be broke...but they'll get by. But part of borderline personality is obsessions and as soon as the promise ring arrived, my daughter wanted to get married right away. An engagement ring came two weeks later, mainly out of pressure from my daughter for the guy to get it NOW. And I'm thinking in my mind that this is going to be an absolute train wreck- she's nowhere near ready to be a life partner and support this guy like she should. So when he asked for my blessing, I said no because he was going to get crushed if he rushed into this...he's never seen my daughter at her worst and she's not putting in any work to be able to deal with life challenges. Now my kid has gone full bridal though, she's already bought a dress (that the boyfriend paid for) and she expects us to pay for the entire wedding of 300+ guests and growing. For now, the wedding is penciled in for July. Statistically, this marriage has about a 1% change of being successful due to my daughter's conditions. But at the same time, how hard do I actually push against it? Do I bide my time and let it self-destruct on it's own? Do I support them and just cross my fingers? I don't think my kid can handle a breakup of this magnitude but she won't do anything to better herself so the marriage can work. So what the heck do I do?
