Sorry to rake this up again as all the replies I had were really helpfull.
I have decided to give it one more try...for a few months to see how I feel about him and the situation.
However, now I have discovered that when he had sex with this woman, it was unprotected...this just makes me feel sick. He thinks I'm over-reacting, and that it's "not a big deal" but how can he say that, when he's slept with me since.
Am I over-reacting..or is this another reason why I should be out of this relationship once and for all??
