I know I should give up by now and just get the divorce over with. But marriage is worth fighting for, despite the fact that most people look at you with pity for trying
If you believe marriage is worth fighting for, you should carry on. At least you will address your issues now, to ensure that you don't carry that baggage forward into your next relationship.

Don't worry about other people's pity for you. That is their problem. Your deal is standing up for what you believe and never having to apologize for lack of trying to live up to your beliefs.
