Baby daddy drama

Okay so I’m having a little dilemma with my baby dad our son is only 2 months old and his dad has only taken him once in those 2 months the rest of the time he swore up and down that he would come pick up but never came. He calls me today and tells me that tomorrow he wants to pick up our son and asked him what time he told me whenever he wants. He doesn’t help me raise him, doesn’t give me money, only time he actually buys him stuff is when I ask him to. It’s suppose to be really bad weather tomorrow and I don’t want our son to get sick. And to be honest I’m sick of him deciding when he wants to be a father. I’ve begged and argued with him so many times over this I’m sick of it. What should I do?
