How old are you? If you are over 35 already and do not have a potential marriageable person in mind, the likelihood of you conceiving a baby through IVF will still be high, even divorce your hu*****and.
I understand how you feel. I would think trying to "train" your hu*****and to take care of you, e.g., cooking, cleaning up and other house work, will be more productive. (Trying to forget your hu*****and's error will help too. It is difficult to conceive when woman is stressed out.)
Good luck.
