Yes, there is a DBing application to financial support post separation, and pulling it back. But it isn't about controlling, it is about boundaries. Your post didn't seem to be speaking to that, it came across as should I or shouldn't I? What is best for ME by doing one or the other.
The boundary aspect is: I refuse to fund you leaving the MR. It isn't about controlling her, she can still leave. It is about keeping a clear conscience that you didn't enable her decision because you disagree with it.
See the difference? Should I finance her or shouldn't I to try and control her behavor vs I refuse to finance something that I am morally opposed to.
The latter is an attitude of: "You can leave anytime you want. You are free to go. i won't try to stand in your way. But I also am not going to fund your desire to do so."
