Hi, Well I think you essentially have a choice between maintianing contact which he doesn't seem to realy want anyway and having a more peaceful stressfree life and pushing him for the maintenence and having the idiot around your family causing upset. In an ideal world he'd value his child and i'd normally say kids are better off if they can have a relationship with their father but in some instances that's simply not true and only you and your partner know if this is one such instance.
