Ahhhh, the roller coaster ride. We all know it well. Like AS said you need to have PATIENCE. He will say one thing one minute and the complete opposite the next..it is he confusion talking.
I'm learning to take what my H says with a grain of salt b/c I can't know for sure if what he is saying is true.
I can understand the anger about the "sex w other women" bothering you a lot. Let yourself experience your emotions but don't react until you've had plenty of time to process this new information.
Infidelity is tough but not impossible to get through (at least that's what others keep telling me).
Hang in there, SS. Try not to respond to his texts/calls every time. Be less available while you're finding yourself. Good luck and come here often if need be!
