The fact is that you married too young emotionally and that is telling now. The best thing you can do is to get some counseling together to see if you can have a good marriage or if you have to settle for being friends sharing children. It is hard to lose a first love but as someone once said, a first marriage ending in divorce is a success if it leads to a second marriage which does not. Good Luck to you!!

sometimes.
