My wife has an innate ability to irritate me, is it time to get divorced?

Divorce is not always the answer talk to a counselor first and let him/her know what the problem is, in the meantime get a second job to make up for the money you pissed away. She probably has resentment towards you for that. Yu were out having a great time while she was stuck with the kids. Sit down talk it out and think of the children......
