religion

I don't know what to do or how it started, I don't know what to say to him, I don't know how I got here . 1st off I would like to apologize about the gibberish. THIS will probably be hard to understand but I NEED HELP ASAP, it all started about two months ago I met this guy at a buyback ( movie DVD game store ) near me. I was with my mom buying some movies 🎥. I left and let my mother by the movies she was buying them for my son (4 years old ) she finished buying the movies and  proceeded just tell me the guy at the front that I was cute,  me am I my fathers son just broke it off about 7  months ago, so I wasn't interested. But something told me. To give him my number. My mom went back inside and gave him my number he texted me immediately.everything was going well, then I found out he was a born again C Christian and that he was waiting for marriage (even tho he wasn't a virgin ) Now I believe in god but I do not believe in waiting ....well long story short we ended up haveing sex. He convinced me he wouldn't regret it .... so well I fucked him and now I did not feel bad about it but amediately afterwards he told me he shouldn't of had did it and that he regrets it !!!!! Should I feel bad about it in crying idk what to do in just lost ....
