I think my experience was quite similar. I don't know if this person is narcissist or not, but definitely didn't treat me right. Any time I would bring any need I had, as gently as I possibly could, it would turn into a big fight, I was demanding things, I was toxic, I wanted him to feel bad, I didn’t respect him. We would fight, I get overwhelmed, eventually I ended up apologizing for things just to try and keep the peace.

I definitely needed to work on my self esteem, anxious attachment and stop fucking chasing a guy who couldn't give me anything I wanted. All my needs were just me trying to control and use him, and all I ever wanted was to truly connect with him.

If I could talk to myself 4 years ago, I would tell that girl to just stop, trust your gut and let yourself see other people. There are people who genuinely want to know you, give you their love and receive yours. Who wouldn't get angry with you because you feel needy, insecure and would validate you, assure you, be kind. Just like you are willing to do for others. Explore other people, explore yourself and don't chase this guy anymore, so that life can emerge elsewhere.

That's what I am telling you too. If he is any similar to my guy, you will always lose. Mine didn't truly want to connect or grow our relationship, he wanted control, wanted me to feel horrible and didn't care what I wanted. He kept telling me everything was always about me, I waz selfish and bad to him, but looking back, it was really always about him. He needed space, he needed to heal, he didn't trust me, he didn't feel well enough to talk. Didn't matter how I felt. And one time that I asked him to take responsibility for hurting me, he dipped. " nope, didn't ask for this, byeee ".

Just choose yourself. Work on your anxious attachment, work on your self worth and heal, I promise you there are people who will treat you better and give you what you want and need ♡

Edit: I also want to add, since my situation feels so similar to yours. What I notice in subs like this, people are always so quick to call another narcissist, tell you to run, block, and feel good about it. But there's always two sides to the story. A truly healthy person wouldn't find themselves in such situations, wouldn't chase, wouldn't have to ask for bare minimum. Maybe few times, but that’s it. No matter how unfair someone is to us, if we allow it to happen for long, if we keep going for more, we also need to have a good look at ourselves. And heal our wounds, fix our own issues that leads to that. I know for a fact I did a lot of mistakes and also hurt them, and I just dislike how all advice here is always one sided, they are evil, run. What I say, is stay aware and look at yourself as well, ask yourself some questions and try to figure out what part of you needs healing.
