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 I 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.
