Ashley,
I identify closely with what you say. I am in a similar situation. I don't know the answer. We've both struggled with finding a way to deal with my gender problem. We've been married for over 35 years and we're still very much in love. Even though she loves me and will support me, I know she won't stay with me if I transition. I've tried various means of coping, and, so far, I've gotten by ... sometimes it's one day at a time. I tell myself if I can get through another day, I'll feel better. SOmedays I know I've gone over the edge and transition is inevitable only to pull myself back to try another day. Who knows how long this will work.
I know that I would give my life to make her happy. In some ways, I do that every day. I don't know how I can be so happy and so miserable at the same time. I'm very happy with my marriage and family, but miserable with myself being male.
I don't have any answers for you, other than to tell you you are not alone, and some of us are still trying to make sense of our lives.
Good luck,
Steph
