My girlfriend of 4 months normally has mood swings that can last up to 3 days normally ranging from 1-3 days. 4 times these have been swings where she wants to break up or does breakup with me, we will meet up to give our stuff back and she comes crying and apologizing explaining that they were not here true feelings and she had a swing of hatred to everyone around her mainly me, when this happens she comes up with bs reasons like “our values don’t line up” or something vague like that and never tells me specifics and doesn’t want to talk about the breakup or make it simple she will be aggressive for no reason. Is it normal for people with bpd to unexpectedly have a mood swing last much much longer? She’s in one of these swings now and it’s been 8 days, it came out of no where I don’t want to go into details but she’s contradicting herself and is unneededly angry at me while mere hours before she was telling me she loved me and that morning we actually had just sleept together (in both ways) and she went back home after taking my hoodie telling me she loved me many times and kissing me bye a countless number of times, then that afternoon out of both were was done and in a horrible mood and causing quiet a scene, I’m scared she won’t break out of this one like the others and instead never come back to me out of embarrassment or the thought I’ve moved on. She gets angry when I try to contact her. She’s blocked me on most things, even though I’ve only tried one time after she told me to leave her alone a week later.

Tldr is it normal for someone with mood wings that last 1-3 days to get a mood swings that lasts Much longer out of nowhere? Espeaciially when provoked by stress, pms and other things happening in there life that cause anger or other emotions, just general overwhelming things?
