How pathetic

I can't believe I did it again. I still keep disappointing my wife over and over. I say that I will do what she asks and then I turn around and do the opposite and it ends up in an arguement. I just don't understand why this is so hard for me to accept.  I know that I shouldn't be playing games but I just can't seem to help myself.  I gave myself permission to go and play while she was on facebook. I know that at we agreed on no playing games until I was back in the bedroom
