Usually if someone can't keep their story straight then it usually means they're lying.
The ONLY ways it's possible to go from managing 20 people and going to the co-owner/administrator to managing 6 people and just dealing with issues is if he got demoted at work or 14 people were fired all at once or both things happening at the same time (highly unlikely).

Did he say what college he got his Ph.D. from and what subject he got the Ph.D. in? (That can easily be traced by looking up the college online and seeing if they offer Ph.D. degrees in that subject (that is if that college actually exists!) also you can contact the administrators and ask if someone with his name ever attended the college if any of those three things comes up with the answer "no" then he's lying)
...... as for him breaking up with his ex because she didn't want a baby if he was TRULY in love with her then he wouldn't have broken up with her (I have an uncle who's been living with his girlfriend since I was little and when she said she didn't want a child he stayed with her even though he considered becoming a father down the road if the relationship didn't work out).

I TOTALLY understand what it's like. I met a guy online (through an online dating site) and we talked online and through letters and after a while he stopped responding back to me and I finally had to leave him a message on his voice mail and at his job and he finally emailed me back saying that he couldn't do it and that he and his ex got back together (that was a week AFTER he left me hanging in IM while I was having a panic attack!). The last thing he and I talked about was getting together and then I got the email saying for me to quite calling him (I had only called him twice after he told me I could call him if I needed someone to talk to!). It hurt so badly....and to leave me hanging like that. The worst part is that he kept going to the dating web-site while he and I "together" and right after he dumped me. I didn't even know he was even considering getting back in touch with his ex..... I didn't even know he had an ex. He told me that he had to sell his truck in order to go to college online (he was even working at the time and some online colleges will let you make payments) and that he had to have friends drive him around if he needed to go shopping. I still don't know how he was able to get to and from work without a car/truck.
