Great thread!
I think the real test for me was many years ago when I fell in love with a close male friend who was "involved" with me and me with him in one of these relationships where he wasn't sure whether or not to pursue his other side. He knew he loved me, and we were close. We had been through so much together already, but he was off and on with our relationship. He knew how much I loved him and felt for him because I had no problems telling him. I was patient and supportive, but in the end he left and we haven't had contact since.
The conflict with himself was too much to handle and so he turned his frustration on me, and used some rather hurtful words towards me. Know what though? I never held a grudge. I only felt compassion for him. I only felt heart-broken while also telling myself that he just needs time. Time has passed and I can only hope he is happy where ever he is, and with what ever life he has built for himself. This isn't a guilt trip towards him on my part, nor is it sarcasm. If he is happy in the world, then I'm happy and at peace.
This whole fiasco is what ended what I was hoping would be my attempt at transition to being a woman. I was coming so close to telling him and actually starting transition with him by my side. Now I am at the point where I feel I can move towards that transition again. So, knowing I am a woman, for me, came earlier on in my life but was strongest at that time in the past. I knew when I was in love and I felt like it was very natural, and I felt good with it. That's what makes a man or a woman, I think, is knowing who you are and being secure with it, no matter what body you were born in.
It's embracing the mystery that lies ahead.
