Family troubles baby daddy now wants to be a dad

So he hasn't being in touch or anything he broke up with me when he got me pregnant and just ghosted me blocked me ect so I posted a photo with one of my best friends cousin just to be a bitch and wind him up so now 8 months later my son's dad has got in to wanting to be his dad and wants a DNA test first I was saying no as I didn't want him to have anything to take to court cause his family are crazy butttt he's agreed that it will be my email my address ect that the DNA kit will go to and the results so I'm in charge but he's paying for it yano here's my problem this guy broke my heart I had a threatened misscarage cause of the stress ..my parents was their to pick up the pieces and build me back up they even built an extension on their house so my son could have a room downstairs with me (we've now moved out and got our own place tho) but I know how much my parents hate this guy and how their so against him being in my son's life cause he generally is a terrible person but I feel like he should have a chance to be a dad ? Atleast while my son's young and he won't know if he comes in his life and leaves you know I told my mum he got in touch about a DNA test and just told her I didn't reply I don't want to tell her the truth because he's a very weshy washy person like hell change his mind real quick so I don't wanna tell her and then he doesn't go through with the test or meeting regular with his son

Stress sorry for the rant 😭 opinions...?

Once the DNA test comes through and shows he's the dad we are going to make a schedule of visitation.
