I dont want to be the bad guy here.

I would like some real honest opinions please.

My boyfriend used to be with a girl who had a 4 year old son from a previous relationship. Without sounding like a b*tch, he took her son and treated him as his own flesh and blood. I wasnt there no. But it is extremely evident that he did.

They had a baby three years later together. Unfortunately they didn't work out - my boyfriend and his ex who he did propose to at one point but the marriage never happened.

My boyfriend has told me about how hard it was to break up because he didn't want to be with her any longer, but he felt like he was losing what he considered his oldest son - remember her son from her prior relationship? He thought of him as a son. And struggled with leaving for a while because of the son. I understand. I couldn't imagine how tough that was to fall in love with a child and then to a certain extent, not be apart of their lives anymore.

He and his ex are pretty civil and I respect that totally. There hasn't been too much tension even with me. I mean I have met her, we have each other's numbers, she has been seemingly OK with me as far as I know. Which is rare so sometimes! So I'm thankful!!

Now here is the issue. For some reason, she has decided that she wants more child support for the child that they share together. Fine. There has never been court ordered rules. He has always supported them and they have worked out their own visiting schedules and it's been great....because a judge shouldn't tell a parent to be a parent. But now, she feels as though he should support her older child too because of their history and that her son sees him as a father. (For the record, even though the oldest isn't his blood, he still will go to his ball game, and give him gifts, and take him for food, and do things with him like it's his own child because he loves him and his mom has never given him grief or anything about it!)

Just now she wants actual financial support for her oldest child because she sees her ex as his dad.

I personally think it isnt his responsibility to. I think its fine to keep the relationship he has with him. But this may sound mean but it's not his kid to support. Am I wrong??!?!

He's really struggling with this btw
