Breaking no contact

I’m exactly 5 weeks into a breakup and contemplating breaking no contact. We were only dating 6 months so I shouldn’t feel this invested but she was really nice and I just felt she pulled back anytime we made progress and I was really bad at communicating my needs and feelings. I don’t think she’d want to start again but feel like I want to at least acknowledge my part in the dynamic ending as it’ll give me some sort of closure. But I don’t know if I’m just doing in incase she texts back that she made a mistake and wants me back 🙃
