I miss my ex

I dated her for around a year before she broke up with me, she was the first girlfriend I ever had and it broke me. But after a while I got over her, and then she reached out to me, said she wanted me back. So I said yeah. We talked again and eventually went out on a date. It kinda sucked though cause she brought 2 of her friends. One of them I knew and was okay with but didn’t know the other. We had very bare conversations and eventually ended up sitting next to each other in silence before I played pool with her friends. It was a terrible date and yet even after rejecting her after it I want her back. Cause she feels right for me, we have the same music taste, she matches my energy, she’s interesting and funny and smart and pretty but at this point I don’t even know, I like her but I feel like I’m not allowed to. And I don’t wanna be that guy to be obsessed over his ex but I am. I want to reach out to her and just ask her to try one more time but I don’t know if it’s a good idea, if she’ll laugh or if she’ll just reject me to get back at me or something stupid.
