I feel that way every minute of every day and night that I am with my wife.
And yet I will constantaly ask myself:
Am I doing enough?
Is she happy with me?
Did I make the right decision?
Is she uspet at me?
Etc...Etc....

So yes because of my mental instability I have the potential to seriously jeopardize this marrige and friendship I have w/ my beautiful wife.

I understand your situation... And unfortunately, alot of times you just have to go thru the motions. To keep the peace within yourself and your partner...
