This is my first time posting on this website. I am in need of guidance, mostly because I feel guilty for my actions.

I became very good friends with a co-worker. We talked about everything we were going through in life and became each others confidance. We expressed our physical attraction to each other, and within time we started a sexual relationship. It was not frequent, maybe once a month. We did talk or text everyday.

He told me (long before our sexual relationship started), that he was in love with a girl that lived in another state. He told me it was hard having a long distance relationship, but they were totally in love. He had dated this girl in high school. then college and ended up going their seperate ways. He looked her up years later and they reconnected. (We are both in our 40s)

I know it was not wise of me to engage in a relationship with him, knowing he loved someone else, but I truly believed he would not do this if he was really in love with someone else. I thought he would realize this with time. I ended up falling in love woth him. I told him I had developed feelings and I was having a hard time seperating the sexual relationship from the friendship. He told me the friendship always comes first, and we would stop the sexual relationship to save the friendship.

Here is the part where I messed it all up. Last Wednesday while at work he told me he had to go home and pack becuase he was going away for a long weekend (the city where is the other woman lives). It hurt me so badly as he hadn't talked about her in some time.

I told him I only want to maintain a professional relationship. No more friendship as I was too hurt to deal with it. I told him he had no morals and I felt bad for his girlfriend because if he truly loved her he would not have sex with me. Needless to say, the friendship is over. I feel horrible. I feel like I should have just stopped the sexual relationship, but at the time I was so hurt and so angry I could not deal with maintaining a friendship and hearing about anything that may further develop with this girl.

What do I do?? Do I apologize or do I keep my distance?

Thank you so much for your help!!
