am i wrong???

so my baby daddy has 2 sons on the way. i didn’t know about the 1st one till after i told him i was pregnant. i’m almost 20 weeks and he’s been in and out of my life i told him i will coparent but he’s not getting nothing more from me. he doesn’t like that, but i really don’t fucking care what he likes. anyways his other baby mama was going to name her son after him now she’s refusing so all of a sudden he wants me to name mine after him i told him HELL NO. so now he’s blocked me and went on with the “that’s not my baby she’s a hoe” it’s all so childish. but am i wrong for not wanting to name my son after a piece of shit?
