Baby daddy

I hate having a baby daddy. Like one the stigma itself it’s just hard, secondly I never wanted kids but now that I’m having one I have to share with someone I don’t even like. (Yes Ik sex leads to kids that’s not the point of this) now I have to share decisions and names and property and all this stuff with someone who isn’t even helping. I hate to say it but I wish he ran away when I told him, or like slowly disappeared but now he’s here and annoying and not helping just staying here, in the way expecting to make decisions when he does nothing for me or the baby I just, I want to be an adult about the situation but at the same time I can’t stand him, like why stay if you’re a deadbeat still does that even make sense.

So a little more detail he does want the kid he’s happy about it but he’s not making all the steps needed to be a father he’s a deadbeat financially and life wise but he wants the kid so I can’t just kick him out their life. I just don’t know how to do any of this honestly
