So very tough OM, if you looked at my old posts, I have said some of the exact same things. You have had some good responses. Someone, maybe it was SHOKA, used the analogy of oxygen on an airplane. You DO have to, in an emergency, put on YOUR mask first. That is very hard to think of when things seem so bad.
I'll go out on a limb and say a few things that have helped me.
I have changed some of my approach. I ask "Are you OK for a hug" instead of just going up to her even though her startle response is much improved.
I do not overload her with cards, flowers, texts but I do things like a brief touch on her arm as I pass, give her the option to share and be happy when she can, Even just a little.
I look for the positive. My example is that about a year ago, I posted that I was so very upset that I went to great detail to have an expensive dinner out, gift, saying I loved her and her only response was that she was sorry she is putting me through hell. I was so very upset that she did not say the 3 words. Then someone pointed out that she was SHOWING me her love as best she could by acknowledging her PTSD to me in that way, which had to be hard for her to say. Is the glass half empty or is it half full? We all have to decide when enough is enough but I try so hard to look at it as half full.
Do I get "down" sometimes? You bet I do. But I not only acknowledge it to myself, I say to myself "you are human too, this is a lot to handle" BUT then I do NOT allow myself to wallow in self pity anymore. I sure USED to do that.
And talk to someone. Due to my job as a manager and my situation here, I don't really feel there is someone I can unload on face to face. So I use the forum and friends I PM a lot as my support system. That may not work for you but even guys need to have an outlet. It's just that many guys won't admit that.
Take care!
