How Do I Make My Boyfriend Pay For His Purchases?

If you have already talked to him about how this situation makes you feel and why it is important to you (example: I feel afraid when you steal because I don't want you to get into trouble.) and you haven't seen any results, it's time to move on. You can't wait around hoping that he will love you enough to change for you, or be wise enough to change for himself. Chances are you will never change him, and will just waste time and energy trying, only to end up hurt in the long run. Good luck!

Unfortunately by human nature you can't "make him" pur se; but you can definately go after him in small claims court in your local area and bring charges against him for not paying for whatever he is suppose to be responsible for.

Tell your boyfriend that you don't have the money, to pay for his things.
