Does it make sense ?

My unborn child’s father wants the baby to come and then for us to try to work on our relationship. This is my first child but I would think we would be to busy to try to work on a relationship when the baby gets here plus I have 22 weeks left in my pregnancy that’s plenty of time to try to get the relationship together. My question is, would it be better to wait until the baby is here to work on us or do it before ? I’m kind of thinking he doesn’t want to be with me and is scared to say that..
