I think you’ve answered your own question as to staying with this person or not. It sounds like you’re reflecting on the amount of energy you’ve put in & are ready to turn that supply off.
Sometimes our biggest decisions is whether to try & try or stop. After that decision you’ll move on again.

If he is not putting any effort into satisfying you sexually, trying....& you haven’t had an orgasm for 2 yrs....& you’re not sworn to this person or have children with them....ill live vicariously thru you & get my walking shoes.
Wish u the best outcome!
