Does pregnancy question what you do even more?

I brief history. My baby's donor & I had been seeing each other for several months when I started feeling that he was hiding something. Shortly thereafter, I decided to stop seeing him. Two weeks later he got back with his ex (who turned out to be his WIFE)! A week after that I found out I was pregnant. I prayed & asked God for guidance (should I tell him or not).... A month later I ran into him & took it as a sign "I should say something". So I did. He admitted to getting back with her but said it was only for his son & that it didn't work out etc. For about 2 weeks I considered giving our relationship eventually (assuming the other relationship was truly over).... Once again, I started feeling that he was hiding things so I asked him to stop visiting me/us & reassured him that if he wanted to be part of the baby's life he could but she wasn't here yet so I'd just keep him informed via text. Since then he texts me almost daily abt how much be misses me but yet has only asked abt the baby like twice (in 5 months). A couple of days ago I was on FB & he came up as "someone I may know" so I clicked on his page & apparently he & his wife went on a trip for 4th of July (which is sad cause he had asked to take me out of town but I told him "No, you have things you need to take care of before you try to come here & invite me out").... I have not been responded to his texts for abt a week now since they have nothing to go with my baby. My question is, am I wrong? I honestly do not feel I'm keeping him away from my child & if he asked abt her I'd respond but he doesn't. I personally do not want a relationship with him (other than co parenting if he chooses to be part of my baby's life).... Any suggestions? Reality checks?
