I met this guy three years ago at a party. I started to talk to him initially as a diversion to keep this other guy away from me. We ended up talking all night long, and from there we had a one night stand. At the end of the night, he confessed to me that he was engaged and had a kid on the way. But, he did say that he would never forget about me. So, three years later, I moved back to town. The very first night I was back in town, he ended up knocking on my door. I knew that any type of relationship with him would be wrong, and I told him that. But, I still let him continue to come over. Now it's been six months, and I've fallen head over heels for him. He constantly tells me that he loves me and that he wants to be with me and not his wife. He claims the only reason he doesn't want to get a divorce right now is because he has his third kid on the way. I always want to tell him that I can't do this to myself anymore, but every time I get the courage to, I instantly back down. I have my own family to take care of, but I always stress over him, especially since my two-year-old recently started calling him dad. I don't know what to do. Should I believe what he says, or should I just call it quits?
