I have a girl who's the only one of my plates I'd consider LTR-material, but she's too crazy. In-person she's the sweetest little non-confrontational baby but later she gets PMSing and sends sad/angry messages at 2am about how she can't see me unless we're exclusive. I've handled it with indifference and she's always OK eventually (saying "omg how are you so mature? Why do you even put up with me?", I tolerate her because she's high-value).

I told her outright that I can't date her exclusively because she can't be a consistently good girl for more than a month. She tells me that she's getting into prayer and studying and other wholesome self-improvement shit but she always goes back to her mood swings.

Just recently, she called me in a normal state of sound mind and said "I can't see you anymore because it's bad for my mental health and I don't wanna be the crazy girl getting angry at you all the time. I can't wait [for exclusivity] any more". I suspect that she'll come running back in 2 weeks crying about how she misses me, but should I even take her back at that point?

We talk about soft-nexting and treating women like children, but how many tantrums do you tolerate? How many times can a girl push the boundaries before you decide it's enough?
