Hi, this will be a bit longer, but I am really desperate for advice.
Thanks in advance for reading.
Some Information about our relationship, and I am trying to be as neutral as possible. Maybe I am an ass, as she told me last Sunday, which she now takes fully back. I went out with friends and came back 2 hours later than we said, which was ok. I kinda had to wait for my friend to leave because he drove me there, but I guess I could have said something she then extremly angry with me, drunk smoked a whole pack of cigs and cut herself.
Some points she also criticised were that we didn't do things the way she liked it, even though I often asked if she wanted anything different, but she always told me I am the best and everything is perfect.
This is the 5th or 6th time she wanted to start this kind of big fight and started giving me ultimatums. Most were not as bad, but 3 were really bad, breaking up badly. I also already mentioned them in my last two posts in AITA. The bigger ones, in short, I wanted to go boating with friends, she went to a friend to get drunk and get me jealous, telling me maybe she will wear underwear when sleeping with him in a bed. (She once had something with this guy), She later said she was really sorry about that. The next was when I was on a weekend vacation with friends. The first day was fine, but the next few days she texted me constantly, pretty much ruining my weekend, which I had been waiting for the whole year. While also getting drunk and high at a friend's marriage and flirting with other guys, they are telling her how much of an ass I am. She then drove home when I told her not to, and lost her license.
As described in my last 2 posts, I have had some problems with my (ex)gf, the last few days have been extremely draining, and I just want to get over it. I was already done with the relationship, but yesterday she made up her mind and now tells me she needs me, and I have been the best man she has ever been with and doesn't want another (she is about 6 years older than me). She went so far as to threaten with self-harm, abusing drugs and alcohol. Now she is telling me how many problems she is having at work, and her daughter is now also having some smaller problems at school. On Monday, when she was still in an angry mood, she told me she was thinking about going out with my friends and started texting them stuff. She later told me this was a lie to make me angry. She also told me her friends told her to break up with me. This was also a lie, and later I really talked with her friends, and they said she has never been happier and should fight for me.
She is also on antidepressants and got a few benzos prescribed in emergency cases, which I dislike because she abuses them. I am really sorry, she seems too unstable for me. I also have problems with anxiety, and a partner like that doesn't help with that.
The majority of the time, she was amazing, and we got along perfectly, but I am not sure if I can handle this.
I don't want to leave her alone(drinking at work and threatening self-harm) like this, but I was done. Should I get back together with her or leave her? I don't really want to get back together, and most of the time she was perfect, but every few weeks/months she has these breakdowns where she really goes nuclear and really hurts me.
This is also my first real relationship, so I need to know if this is kinda normal, if I should accept this and get back together.
Please Help and Thanks for reading
