An affair with a married man for two years? Well, that was always going to end badly. He sounds like a bar stuard anyway, you're best of without him. Next time you neet a guy... Look for a ring on his finger.

What can I say? You walked into that one.

I suppose it's up to you if you want to walk away from it with dignity or scratching and crawling at him, getting angry and telling his wife etc.
