I'm not going to say whether you should date or not. That's personal choice.
What I will say is you have question why you would be dating. Is it because you are truly moving on or is it a temporary relief. If its to prove something to your W then do you really feel that using someone (whoever you date) like that fits with any changes your trying to make in yourself?
Don't get me wrong, when I found out about the other man and the way my W is throwing herself at him (she still says he has nothing to do with this) and her desire for 'any man, a REAL man' it made me want to go and sleep with anyone who'd have me. But then I realised that's just my hurt self esteem and that revenge sex probably isn't in anyone's interest
