Please do not feel like you are alone. I am in the exact situtation you are. The only difference is that I have one child not two. My little girl just turned 8 on Friday. She is the love of my life and that is why I stay in the situation I am in. We were seperated back in July for 1 month. He then came back and swore it was over (I really don't think it is). During that one month my husband was stupid enough to expose her to the other woman. Now my little girl keeps telling me she doesn't like her and she doesn't want a step mom. It breaks my heart. So I keep telling myself to stick it out so she doesn't have to go through all the pain and agony. The hard part is understanding why he doesn't see what he is doing to our family. I continue to pray that God opens his eyes. I pray alot. That helps me through the real bad days. I have been dealing with this going on 8 months now and it hasn't gotten any easier. If you need someone to talk to please email me back. I find it easier to talk to someone who has been there. Everyone tells me to get rid of him I deserve better, but if you like me it's not about me it's about my child. I just keep telling myself I am responsible for my actions and I know that I have done nothing to deserve what he is doing and I have done nothing to get back at him so I have complete peace. As for him, he needs to deal with the guilt daily not me. Hope to hear from you soon.
