Final update:

After almost of month of no contact, except for that one night when I texted him how it was going, I finally insisted on a sit-down conversation with BF. He was resistant, but I insisted he give me what explanation he could.

So we're officially done, as of a week ago. I don't know if it was the Paxil or just an incompatibility. His reasons include that he couldn't imagine living with my son and me because we have different parenting styles and because he's neurotic about cleaning, and also his job is transferring him and he doesn't want to take me away from here because I have a lot going for me here.

It's been hard. I've never been so hurt by another living person. I never met a man that I thought I could marry. He was my best friend and it all just seemed to happen so fast. I guess I'm doing pretty good, I still cry every day but I am functioning and taking pretty good care of myself. So I guess that's the end of the story. Thank you all for listening and giving support and advice. I really do appreciate it.
