In my opinion, once is too many.With great difficulty and Tact, Today I was able to gather few inputs from my wife, which i am already aware of and need improvement from my side. List of Horrible things I do.
1. Violent (The Recent Incident, in a span of 7-8 years when i got frustrated out of waiting and planning for sex).
2. Abusive at Times (Abused her 2-3 times in a span of 7-8 years for not having sex with me, after I had planned/waited in bed and I got a frustration burst).
3. Financially not strong.
4. Once we fought at time of first child was born, 4 years back.
6. Takes less care of kids.
7. Porn Addict
8. Too touchy
I am not justifying by violence or abuse, Its wrong I know. Its very very bad. And its not regular, it happens in 3-4 years ...
But all this happened in frustration, helplessness, me not in control of emotions or sexual drive.
Otherwise I am usually peaceful and humorous as per others.
