I'm thinking of leaving my wife. I hate thinking of splitting up our family and only seeing my sons part time but I can't stay with her. She had a one night stand with a co-worker of mine. He confessed and apologized to me. She denied it for weeks before finally telling me the truth. I believe that the only reason she told me the truth was because he got her pregnant. I had a vasectomy after our last was born so there was no denying it any longer.

For awhile I thought I could handle it. We worked on our marriage and decided to raise the baby as our own. Now that she's really showing I find myself thinking about them together every time I look at her belly. I picture his cum inside her body, making a baby where I made babies and it's awful. I can't get it out of my mind. It's like a kick in the gut whenever it comes to mind.
