Need support! Conflicted H

[Junsui]

I don't know if this is technically good DBing, but as I just mentioned in my previous post, one of my 180s has to do with finances. Since H has no income, I've been paying all our bills and all of the debt is in my name. However, as a student, I'm not making very much money, and this has been a huge source of stress to me. I told H he needed to cover his part of the bills, or we needed to sell the car, etc. I also told H he needed to get his own credit card.

I've been trying to do minimal contact, but I called H twice today to try to give him the final amount he needed to contribute to bills. He didn't answer either time and has not called me back. Since I gave him a close estimate at our financial meeting, should I just stop trying to reach him for now? Is it too helpful to send a text message or try to call again with the final amount? I feel like I might still be taking care of too much for him.
