WW having affair and pushing for divorce

[DB346]

Met with a good friend early this morning. He has been very supportive through all of this. After that meeting I sent her a text letting her know that on the weeknights I have been spending with our son that I would be keeping him overnight going forward. I feel like every time I take him back to her parents and she doesn't come home to him that I am letting him down. It feels like she is using custody of our son as a way to maintain some control over me, but I feel no obligation to her as long as she involved in the A with OM and behaving the way she is. I just want to do what's best for my son.

It makes me so sad sometimes when he smiles at me and I can see her in his face so clearly. He is such a sweet and sensitive kid. I just don't understand how she can do this to him.
