That could be part of a child support agreement. He should be contributing to his child in a way that benefits his child. Rent helps make sure there is a roof over the child's head and not cash being handed over that could be used for drugs or gambling or baby-momma a new dress/vacay without the child... Which is cheaper each month, 400 for rent or 1200 court mandated cash?

Honestly - He's given you your answer. Take the opportunity to find someone better matched to you and your goals and let him continue paying rent for somewhere he's not living. Now, if it's part of like, a court-mandated child support thing, well, it's not like he can just stop doing that. But you're not obligated to stick around either way.

I hate the term baby mama/daddy. No matter the dislike you may have for that person, that is the other parent of HIS damn child. His responsibility is to provide for his child, even if his child doesn’t live with him. And if paying half the rent helps to provide a good home for his child, then he should keep paying it. I don’t even have kids and think he should keep providing for his child. Cause ya know, that’s what a responsible parent does. If you have a problem with it, you’re the asshole and YDI. How dare you ask him to take away from his child.

Never bet more than you are prepared to lose. I learned that from poker a very long time ago. My personal philosophy is to always call the bluff when someone is blatantly attempting to manipulate me… Legally required or not, a man or woman has an obligation to help support their child. That doesn’t mean either parent gets a free ride - both the mother and father are legally and morally required to share the support for their child… OP, as others have said - You have your answer. You can either move on to eventually find someone without children or a sorry enough person that they don’t support their children until legally compelled to do so. Of course if they are that sorry a human being what do you think they would do if you had their child?

He's taking care of his child in a way that's not paying for her nails and a new phone. If you can't handle him caring for his child you don't deserve the title of bonus parent and really should leave

Don't issue an ultimatum if you can't deliver on the threat.

I say good ridden. You are looking at it the wrong way he is helping to support his kids not his baby mama. You should be ashamed asking a father to not take care of his kids.

Do they not have a state enforced child support payment and they have both agreed that half rent in enough? Half of her rent sounds like it would be a low amount compared to a state determined amount.

He's supporting his children and their mother financially, and you want to LEAVE him? Christ on a ******* cracker, just break up with him now--you're a horrific person and he deserves better. If you want him to choose between you and the wellbeing of his CHILDREN, you are a filthy excuse for a human.

Why would you stay with him if he's doing that, anyway? He's probably doing more than just paying half her rent... if he doesn't live with her, there's no reason for him to be paying any portion of that rent. That's not the same thing as child support. You should have left him a long time ago, honestly.
