Your life is in your own hands. If you are having struggles and issues on this for long, it is better to do something yourself rather than wait for him.
Understand there are some legal aids for divorce proceeding if you have financial difficulties. Not encouraging you to do the divorce route, but you know yourself whether is it worth your while to stay with this man.
Don't need to feel sad. Don't need to ask why he marries you in the first place. There is no certainties in life other than death and tax.
You already acknowledge it is meaningless marriage, so why keep harping on the meaningless marriage? Why not do away with this meaningless marriage and spend more precious time on your kids, extended familiy, career, interests rather than on someone not worth your love?
Take care!
