How do I fight wanting to talk to her again when I know I shouldn't?

My girlfriend broke up with me on april of this year because according to her I didn't pay enough attention to her needs. At the time I did a lot of begging because I didn't want to let her go and we had a last talk for closure. She even told me that even if the relationship couldn't continue she still loved me.

At this point I thought to myself that if I proved I cared enough we could go back together, so I showed up with flowers outside of one of her classes where I knew she was going to be. She did not like that at all and even tho she accepted the flowers she told me to leave and then texted me that I need to respect that she wants to be alone.

After this I honestly went from feeling sad to just angry, she always said that she would have wanted me to fight to keep our relationship together and I felt like that's exactly what I was doing while getting nothing out of it, so from then on I decided that I would go no contact and that I would not break it no matter what, after all if she broke up with me she should also be the one to let me know she wants to go back.

Now the entire summer is gone and what would have been our 2 year anniversary passed by this august without me hearing anything from her. When I was about to unfollow her on tiktok I went through her shares (bad Idea I know) and it was full of posts that boiled down to "I bet he isn't thinking about me at all" or "waiting for that text that never comes".

I know some women are too prideful to go "chasing" a man but at the same time I feel like there's no way I have to be the only one doing the chasing especially when she literally told me to leave her alone. Is this all a game? Did she really expect me to keep bothering her when she explicitly told me she needed space? Was it a mistake to go no contact in the first place? It's all just so confusing and honestly I just wish I could see her again but the voice in the back of my head keeps telling me that if I text her I'll regret it because I already tried it and already got burned. I don't want to keep lowering myself and keep asking her to come back but maybe at this point I'm the one that's being too prideful.
