I forgot to add in my last post that I am, due to my bipolar I'm sure, a very needy person. I do not need many people in my life, infact I am happy spending and talking to only my wife. This places an enormous burden on her, as I can talk emotions and deep and meaningful til the cows come home. Needy makes me clingy, which means that I want to be involved with everything my wife does, which again leads me to smother her and not give her the time out she needs.
This for me has been a life pattern, I am unsure why. I am slowly learning through therapy and other means (my wife telling me the way it has to be for her to survive) that I need to change the way I act. However it often means that I simply internalize my emotions until an appropriate time when I can unload on her again. It sounds horrible, and I know I do it, but its a really hard life pattern to change. Its one of the reasons I am on PC, as this gives me an outlet for my emotions and lets me interact with others without the need to "preform", ie act and behave the way other people expect.
I wish you all the best
