what do I do now?

So in have been celibate for almost four years and I recently met this guy. He was really nice and we clicked so well. We went on a date and hung out. He ended up talking me into having sex( without a condom) and now I barely hear from him. I was okay with just having sex with him but he doesn't even do that. It's like he really wants nothing to do with me. He has become a HUGE a-hole and I seriously don't know what to do. I believe in soul ties so it's hard for me to just let him go even though I know he is no good. Plus I have 9 days until my period so idk if I'm just being hormonal or emotional. If anyone has any advice or support it would be great
