I think that if you are going through a divorce right now, you might need some time just to be alone, to figure out what you want, and to be yourself, without another man.  Having good friends is one thing, but being sexually involved with another person just seems quick.  If you knew that you wanted to be with him and that he was the one, then I would say go for it.  But, it sounds like you aren't sure what you want, which is very understandable for someone who is going through a divorce.  Enjoy being with girl friends and be yourself.  Give yourself some time to recover and become undamaged.  Good luck.
