Hi Dee,
I'm really sorry that you're having to be put through this, but I know where you are coming from. Some wives will not understand,. In addition, they feel betrayed, fear being abandoned, as you mentioned; will call you a liar, even though you've tried to be honest. The question is how long can you put up with it, assuming you still love her and financially, can you get away. It is a form of abuse, I know, I live with it too.
Does she work? Can you really afford to split? I'm just a few years older than you and have held off transition because my wife isn't working, she home schools our son. financially, two households would be impossible to support.
So what do you do in the mean time? Don't know if you have any children at home, but I try to avoid any alone time because that's when all the vitriol comes out. Try to keep someone else around. I've gotten to the point where if she starts on the phone, I politely say I don't need to take this abuse and hang up nicely. No, I haven't been kissed in over four years. Sex? That's solitary. Please feel free to vent here or PM me. Know that you are not alone and that WE here care about you as one of our sisters.
I know its hard.
Big Hug,
Traci
