He’s really just mad that she got married and that SHE isn’t giving him the attention he wants. This is what a lot of these baby daddies will do lol they don’t want to commit to u properly, but also don’t want u to really have anybody else. He isn’t mad about not talking to the kids, otherwise why would abandoning them altogether be his go to threat? U can’t love your kids THAT much if u threaten to do that so lightly. He also said he’d gone 2 yrs without being in their lives before.
