Love is a decision - my story

[Seeker7]

OK, I need some advice here. I am almost positive that my W hooked up with POM2 on Sunday when my kids were out of town. She is keeping it hidden but from all of us and all the signs are there and some mutual friends it is pretty sure. I am tired of playing the nice guy and not confronting her on this. That is not in my character. I never do this. She keeps telling me she is not having sex and not seeing anyone. She just tells me these things with out me even asking her about them. To me it is a sign of guilt. I know she is lying and I keep validating her. But I feel like a door mate now and it is bugging me. Should I stand my ground for my morals or just ignore it? Should I tell her that I do not stand for this?

I have not called her in 3 weeks and am not going to call her. But when she calls should I even mention my moral convictions on this?

From what a couple other people have mentioned is that she is just looking for hookups and not a relationship. I am not sure though.
