I agree with everything OT said.

This is almost exactly my story 2 years ago.

Know one thing: if your H is MLC or something like that - you DO NOT know who he is NOW. The faster you accept this, the more you can deflect some of the shock and hurt.

He is capable of anything and everything. Likely he knows what he's doing is NOT innocent, but he doesn't want to get the crap from you. He acts innocent when he's 'caught'.

He's pushing himself on another woman - he knows what he wants and what it can lead to. Trust me on this, my H did the SAME thing.

Take care of you.
