I cheated

In June I started talking to a guy outside of my marriage. We met up and had immediate chemistry we hooked up, and quickly started a relationship. We were both married, and I guess we found what we wanted from our spouses in each other. I too quickly fell for him, and he told me that me loved me. Wanting that love, affection, attention and great sex that he was giving me I fell fast and hard.

Long story short, my husband found out about my affair, and I decided to end things with the "boyfriend" that lasted about a weekend. On Monday he asked if he could take me to lunch, and we talked and he asked if we could be friends. Which I knew that wouldn't last, but I couldn't not talk to him. I was addicted. Things continued for a month, and I felt as though we were getting closer. He had started talking about starting a life with me once his divorce was final. My husband and I are now in the process of a divorce as well. 

On Thursday everything changed. That morning he was talking to me as usual, and had confided that he wanted to try to have a baby with me once everything was finalized. We got off of the phone and that evening he called me and told me that he was going to work things out with his wife. I have been blocked on his phone and am heartbroken. I know I need to move on, and I do hope that he and his wife can be happy. But I don't know how to let go.

Also, I am terrified that I may be pregnant. We had unprotected sex on Wednesday night and he came in me. I had forgotten a couple of days on my birth control and didn't know that we would be having sex that day or that he was going to cum in me. 

Anyway I guess what I'm wanting is reassurance that I will be okay and I will move on. If I am pregnant do I contact him or just let him be? Fuck I feel so stupid and foolish.
