GTO, if he tells you he is in love w the OW is bc he's not sure of it. He's looking for a reaction. I think it's very likely this is not an EA only anymore, though...Sorry, but that's my impression. If it has remained an EA, then it's bc he's ambivalent and unsure of leaving the M. Especially if he said that he'd be done if the EA turned into a PA.

I'm not inside your H's head to know what he's thinking, and you're not either. So ask yourself if you want to save your M. If your answer is yes, then continue the GALing, etc. Continue sending him love (not telling him.) The best way to send him love is to let him be. Let him follow whatever path he feels it's best for him. Release the need to fight this. As soon as you do this, he'll feel the lack of pressure and might start approaching you in a more positive manner.

Hang in there, my friend.
