I had unprotected s** with a girl who I was having an affair. She didn’t know I was married (or that I had a child just a few months old), but she suspected I wasn’t being honest with her.
However, she didn’t take birth control and became pregnant; she told me she had an abortion and wanted to break up. I suspected she wasn’t being honest with me and so I agreed, but also lied to her (I am well practiced at it by this point) and convinced her I would leave the country.

A year later she has had the baby and I am still pretending I’m in another country and unreachable.
