How do you feel about giving your boyfriend money?

How often have you given him money? If this is the first time he's asked you, then I wouldn't think much about it. However, if this is one of many times he's asked you, then I would begin to consider that perhaps there are some red flags.

Being in a relationship with someone doesn't mean that you are dependent on someone. Rather, it means that you are both independent individuals who commit, work together, and contribute equally. If you give him money once, and he pays you back, then it's fine. But if he's done it on multiple occasions, then I would really recommend stepping back and keeping a sceptical eye.

Does he constantly ask you for money? If so, then I wouldn't do it. It's his responsibility and he should understand that he should save his money for child support/bills/payments/etc. He shouldn't ask his girlfriend that he's had for a few weeks(?) for money. Like you mentioned to withhold all funds and let him handle his financial issues himself. Unless you know he doesn't have enough money to pay for child support and you feel like loaning him the money until he's able to pay you the money back. Other than that, I wouldn't really help out to much - it's his situation and not yours.

I wouldn't have given him any money in the first place. He's an adult and should take responsibility for himself. It sounds like he's using you. Not only should you withhold funds, you should break up with him.
