Very sorry to hear that.
But you're absolutely right. One person cannot make a marriage work. If he is not willing to try, then there is nothing you can do about it except keep the door open if thats what you want to do.
The only good thing is that you have to be separated for 1 year before you can apply for a divorce, so there is still a year for things to change. He may realise that being apart is not as great as he thought it would be.
