Kim,
My short answer to this question:
</font><blockquote><font size="1" face="Verdana, Arial">quote:</font><hr /><font size="2" face="Verdana, Arial">is it possible for a man to make a mistake like this and still be capable of being faithfull to someone?</font><hr /></blockquote><font size="2" face="Verdana, Arial">is yes.
My quick advice to you is to cut this man out of your life. You're not married to him, and you're definitely not starting out in a great situation. Find someone who you won't be carrying this baggage with.
I would also suggest that you get one of Harley's newest books:
Buyer's, Renters, and Freeloaders, as well as take a brief test that appeared in the latest edition of the MB newsletter (posted
here). To have a successful marriage, you need to follow the basic four rules of MBing (sustaining romantic love):
Protection (no lovebusting)
Care (meeting important emotional needs)
Honesty (absolute)
Time (15 hours/week)
I normally tell people in your situation to run, because you're not married. You don't have to put up with this situation. I understand that you have a feeling of committment, but it's not the same thing. Add to that the fact that he will be a professional athlete---you're very unlikely to have a marriage that survives. Pro athletes have a very difficult schedule that makes that 15 hours/week quality time nearly impossible (it can be done). Pro athletes are often in situations where affairs are easily accessible---women are "available" and several of their collegues are doing it.
Add that on top of the fact that he will be caring for this child and have a relationship with her for the rest of his life.
Wish him good luck, and walk away.
