I don't quite comprehend the combination of citing that she "just won't leave" and also admitting you're continuing with affection and intimacy, paying for things and eating her cooking.
"Just won't leave" implies that you've told her you don't want to be with her, yet that list implies you either have not or you've effectively nullified that sentiment by continuing to be in the relationship basically to the fullest extent.
It's strange.
I am very glad you brought this up. I do feel in a constant state of conflict. On the one hand, I feel obligated to do everything a husband is expected to do according to the holy scriptures, and I follow through on those obligations. On the other hand, she may regularly do things that trigger my accute realization that it was all a mistake, like refusing to convert, or refusing to go back on bad investments. Then I tell her that she tricked me into marriage under false pretenses by pretending to be a Christian woman who upholds Gods will namely submitting to her husband and converting to the right religion. And I tell her I deeply regret marrying her. Then usually nothing happens and things carry on carrying on. I feel trapped by my own lack of due dilligence up front to tell you the truth, which is why I can't find a stick to proverbially beat her with.
