That's a really difficult situation.

My ex-husband used to be incredibly resentful about me spending money on T - and he never even had any control over my money. We maintained separate finances throughout our marriage, so I was free to make my own decisions about money. That left me realizing that the issue was way deeper than money.

Based on my own experience, I wonder if it's truly a financial issue...or if there's more to it than that. In my situation, I learned that my then-husband felt threatened by me being in therapy, etc.

I'd imagine that exploring the topic together - both sharing your honest feelings (not judgments, not thoughts) - and having some willingness to compromise would go a long way. (Sacrificing my therapy was never an option, so I am not suggesting that at all. Merely suggesting that exploring the feelings and wondering what can be done to help bridge the gap.)
