baby mother concerns πŸ™„

My boyfriend is always bringing up his baby mother, she does not live in the same state as us or his kid but I find it sad he talks more about her than his own kid who's now 5. He talks about her more. I know that's the mother of his child but he's not in his child's life ( I know sad) like at all. He doesn't make an effort. Main point is I get it if he brought up his kid but is his baby mother necessary? Or am I being extra πŸ™„
