Leave You For A Woman....Maybe...

Most of us in the lesbian community were originally in a heterosexual relationship, due to peer pressure & the expectations of our families, but it is normal to have crushes on other girls during adolescence: these feelings are usually put aside when we become emotionally attached to a guy.
At that point, things can go two ways: you find & take what happiness you can & possibly live together “happily ever after”, or you find yourself unhappy in your relationship & leave him. You may well then try other guys & find one you can live with contentedly, or you might try dating another girl. Girls rarely look back after living with another girl, ever if they have to search long & hard before finding their perfect match.
Things are more complicated when children are involved, though. I may be a progressive feminist, but I still believe that children are best raised in a family environment with a mother and a father, a view that is not shared by all lesbians. The truth is, most of us do stay with the father of our children until they reach college age, at which point there is little left to bind you together.
Whatever you decide will affect those around you, but ultimately it is your right to seek happiness in your life.
