I was hoping to use this as a positive diary of what has been going on, but it doesn't appear to be that way.  Guess I should have known that it wasn't going to be a happy joyous ride to finally being me.
This morning on the drive to taking my wife to work, I was talking about how I was at my parents house last night.  Still working on if I should tell them or not as they are fine with my oldest coming out.  My wife then tells me it may not be a good idea to reveal everything that I am going through.  She said I should do it in stages and not mention that I am actually wanting to transition all the way to being a woman or that I have started HRT.  She thinks it would be easier to say that I am transgender but still make them assume I don't plan on going further.  Her feelings are that they will be embarrassed, think I am too old, that I have a wife and kids, a good job that I could lose, etc...
That all makes sense but what hit me was what she followed that statement with: "Like all the feelings I had.".  See I knew about the old part (she feels I am too old...), the wife part because we have discussed how she can't be physical with me as a woman (which I get as she isn't a lesbian...), the kids she worries will see me differently or have issues with their friends (and family of friends...) if they find out that dad becomes a mom.  It was the "embarrassed" part she never mentioned before.  I asked her if I embarrass her and she took a while and said no but it wasn't very reassuring no. She said our daughter is different because she is starting her life but me...well I guess I should just sit out front and wait for the grim reaper to arrive.  Okay that was a little too far...
I guess she really feels why bother after all these years.  Why change things now.  Why ruin a good marriage over something like this.
The hard part is the mixed messages, which if I really think, I have mixed emotions about all this too.  Sometimes I think I can do this...others why bother as I AM too old to be starting over.  I have a good relationship with my wife and kids and family/friends.  The other day she helped me get women's underwear for me and we bought a couple sport bras to help when I do my walks/riding.  
I know she is scared and afraid but so am I.  I really do love my wife and family and would do anything I could for them but I have tried so hard to be who they think I should be as a man/husband/father.  It is too hard to watch others living their lives the way they want/feel.  Somedays I really had this transgender stuff.
Sorry...just having a bad day.  Hopefully tomorrow will be better.
