baby daddy

I don't understand why baby daddy always try to accuse woman for having another boyfriend well me and my baby daddy broke up maybe April 2016 ... but I swear everyday he always wanna try and say I got a new boyfriend which I don't and not planning on it ..tbh I think he trying to get me mad or jealous which isn't working cause I really don't care what his lying cheating ass doo ... since the time we haven't been together he haven't ask about our kids we got together as it is now only thing he ask for is $$$ which I don't help him and told him maybe it time to get a job to support yu self and he keep saying I just want child support lol first of all I don't want his money all I wanted him to do is be there for his kids... but noo he won't even do this pussy is more important then having a relationship with yu kids ... but I'm so fed up and I don't kmow what else to do cause I don't want the child support from him just wanted him to be there for his kids which I don't see happing I guess u can't make someone be apart of there life any advice
