He's lied about being intimate with the other person online. If he got on the phone with this woman and did the same thing wouldn't that be considered cheating? If he went to a bar and did the same thing wouldn't that be considered cheating. Its one on one, its secrect, its sexual, its emotional, its cheating! And the worst part is you're feeling all the crap from it, not bloody fair, IMO action needs to happen immediately, lay it all out in front of him baby, respect yourself because he obviously isn't.
