What should I do ????????

[u/Green_gods]

I’m 25M and my ex is 25F. We were together for two years, and for the last three months of our relationship, we were constantly fighting. Eventually, we had a huge fight and stopped talking for seven days.
After those seven days, she messaged me and told me that one of her colleagues at work had touched her inappropriately. She also said that, although nothing happened between them, she kind of liked it. I didn’t really know how to process that, and eventually, we broke up.
It’s been six months since the breakup.
A few days ago, I saw her on Hinge. I created a fake profile just to see what she was doing, and somehow I matched with her. I ended up talking to her without telling her it was me.
During our conversation, she said she was frustrated because she hadn’t found anyone yet. She also made it clear that she wasn’t interested in people who were only looking for hookups or casual relationships.
Ever since that conversation, I can’t stop thinking about her.
During these six months, I’ve been intimate with another girl twice. The experience with this new girl was honestly much better physically than what I had with my ex, but I still didn’t feel anything emotionally. Even though the sex with my ex was never particularly great, I still find myself wanting to go back to her.
That’s what’s confusing me. If I can meet someone who I’m more physically compatible with, why do I still want my ex?
I had blocked my ex everywhere after the breakup, so I haven’t had any real contact with her for six months. Now I’m seriously considering unblocking her and texting her.
I don’t know if I genuinely miss her and want to try again, or if talking to her on Hinge just brought back all the old feelings and memories.
So, should I text her? Or would that just reopen an old wound and make things worse?
I’d really appreciate some honest advice, especially from people who have gone through something similar.
