I know this is bit of victim puke, but I want some feedback, since it's the first time I'm going through this (22 years old).

We have been seeing each other for 6 months. She is a complicated girl, some issues with depression, used to be quite promiscuous, but also drifted into relationships quite quickly.

She told me in the beginning that her relationships tended to go down south after 6 months, which happened again with me. Probably a self fulfilling prophecy.

She just texted me she is coming over to pick her things up.

We had 3 bigger fights in the last 1-2 weeks. I'm no person to fight, I hardly ever fought with anyone outside of my mother/sister/father.

The first one was about her calling my friends "either stupid or assholes" which I told her was a no-go to me, since she doesn't even no them. I just saw that that a friend of mine only invited one of his former to flatmates (girls) to his house party and I was wondering why, since I know all of them quite well. Anyway I shared that with her, and theorized that it probably had to do with money/contract stuff while moving out. She said they probably had a thing for each other, which I was very sure of that this wasn't true. I told her that it most likely wasn't anything sexual, after which she said my friends are "either stupid or assholes".

Second one was, when I acted a little butthurt, after she (I felt like) insulted a drawing of my sister. "It's good, but if it's supposed to be a stairway it's wrong". I value my family and would always give out criticism with care, that's why I overreacted and felt attacked. Just typing that out made me realize that this one is a real big fuck up on my part.

Third one was me scratching of a burned toast, to which she complained that crumbs were falling on the floor and if I could scratch it off to the other side. I pulled the plate a bit more towards the center of the table, continued scratching, which she took as provocation on my part, since I didn't switch sides. I did after the second time she told me, since I didn't think of it as such a big deal at first, but the fight was already coming on. Anyways she started bullshitting about how I don't care about what she says, so why should she care about what I say. That she doesn't give a damn about what I think or feel. I should have left by myself and was about to, but she said "it would be for the best to leave now, otherwise I'll say bad things", which took away the power of me walking out.

The nail in the coffin was last night. We were invited to a house party of a friend of us. I wanted to go early, since I haven't seen many of the people present in a long time. She wanted to pre drink with a friend of hers, to which she invited me 1 hour before it started. I declined, since I had other things planned. I think that was the first strike in her eyes.

House party was kinda boring, but many friends of me whom I wanted to talk to. She didn't know too many people and isn't too keen to meet new people. She said "I'm leaving at 1am to this club" not even asking me, but just stating that she's leaving. I probably have too much pride sometimes, but I'm not running after her, if she's not even asking me. If she asked me something along the lines of "I think this is boring, my friends are going to this club, do you wanna come?" we could of talked about it and could have found and arrangement that would have made us both happy. She just wants to make her more important with not even telling me, whom she's going with and stuff. I told her that I would probably come later, but also would like to go to a different club.

She basically left without telling me goodbye. Texted me that she met up with her friends, and they weren't going, because they wanted to drink some more, so she would probably go home. She then expected me to magically know that they did go to the club. I went there, because I kinda promised it, but she was leaving by then. She was extremely pissed off at me, because in her eyes I was too late. It took me 25 minutes from getting the information that she did in fact go to the club to arriving there.

On the way home she accused me of only doing what I want and that she doesn't want to be dependent on me. That I always want to keep all my options open and can't make decisions. And then some hamster arguments of why I'm solely the bad guy.

I could go into much more detail, but I don't really want to. I just can't wrap my head around this situation.

So to you more experienced folks.

In a situation like that, should I leave the party with her? I feel like I neglected the "keeping her safe" aspect of a relationship by letting her leave alone. But she also didn't respect me, by basically stating that she would leave at 1am, leaving no room for my input. I'm not her lap dog.

Am I to sensitive with my boundaries when it comes to my sister or friends? I know that I should be an oak, but am I expected to swallow stuff like that as well? Is that already being too soft?

I just wanted to let some steam off and would appreciate any feedback.
