Friends with Benefits

It ended just recently, a mere few days before I found out I was pregnant. I’m about 4-5 wks preggers and I told him in an email. The relationship ended because he said I was a nobody and I didn’t mean anything to him, after telling him off I deleted his number. So now all I can do is email him. He doesn’t want anything to do with me which is fine because the feeling is mutual. I want him around for the baby’s sake though. I don’t know what to do in this situation. He’s acting like he doesn’t want to be bothered with the baby. He doesn’t even know who his own biological father is so I would think he would want to break the cycle. What should I do? Should I continue bothering him about the baby or just leave him alone? I want to do what’s best for the baby.
