No need to debate the pro's and cons of a marriage here... the fact remains you want to get married and he doesn't... only one of you can win... either you don't get married and he wins... or you do get married and you win...
He won't be happy being married... and you're not happy being unmarried... one of you will have to give up what you want...
So far it seems like it's you...
Can you live with the idea he may never marry you?
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
- James Allen
