Apparently I'm a sub now.
O_oWhy is it always the man that is fucked up with sex, it is never the woman, is it because they are the sexual elite? I think not.
In all seriousness, however, as a person who has been through it from the child's point of view, divorce sucks no matter when you do it. To me, the when is less important than the why.
Leaving your marriage to be with someone else is a risky reason, because that someone else may not be there. Ask yourself if that other person wasn't there, would still rather be alone than with your husband? If the answer is yes, you would be happier alone than with him, then divorce might seriously be considered. But if you're only leaving him to be with another, keep in mind the very real possibility that that second person may not seriously commit to you, either, and then you'll wind up alone.
The grass is always greener on the other side, and you don't know what you have till it's gone.
Oh, I should add that my mother never did find someone else to be with- and she is still grateful for her freedom from my very angry father, every day. So for her, divorce was the right choice. I can't possibly know which choice is better for you, so I'm just offering my opinion.
