I thought we had a great marriage. We both worked hard to pay off his debt and to buy a house. We planned for a baby and now she is 3 months old. Well, 3 weeks ago i caught him sending face and nude pics to another MAN. Where he works and all info. He told me he was molested at age 12. And that it was a joke and he wanted someone else to feel that pain that he had by standing them up. I'm devastated. I've lost trust. Feel betrayed. We bought our house 8 months ago. I had a good job and quit to be a stay at home mom. Now I feel as I'm stuck. No job. I can't provide for me and my daughter. I thought we both wanted the same thing. All I want is what's best for her. I've debated between staying agoing back to school so I can support her and I of need be (work it out with my husband) the other part of me just wants to leave. Pick up a job and try to make it. I just don't know what to do. I feel stuck. I want to love him but I feel that I deserve better. Having a baby and him doing this to me 3 months later.. It hurts. More than anything. Part of me wants it to work. However this is the 2nd time he has done this to me (1st we were married almost am year). Swore he'd never do it again. Now we're in the same boat he'll never do it again, yada yada. I don't believe him. But he won't admit anything other than it was for a joke and to hurt someone and that he is battling depressing. He is seeing the doc for depression meds. I don't into what to do. How to handle any of this. Any advice?
