The way that you state it makes me wonder, how long has it been that you've been apart from your ex? That's a big factor. Thing is, I don't think anyone should rush into a serious relationship soon after a break up of any kind that was serious.

I have been separated from my wife, working on the divorce for over 18 months now and to be honest, I'm glad I didn't ever get into a relationship the whole time. I know that even at this point, I'm not at all convinced I'm ready for that.

Be patient, take the time to work on you, be independent and do things you've always wanted to when you were married but couldn't. Take care of yourself and when the time is right you won't have to ask the questions anymore.
