I am so happy for you! I support you and hope you have a healthy, happy relationship with your girfriend.
I know divorce is difficult no matter what the reason; still I'm sure it was the best thing for both of you. I know from personal experience that being in a marriage with some you don't love and aren't even attracted to is such a painfull way to live.
We have a GBLTQ site here that you can always go to if you need support.
