There's a few things... my spending (though I am getting better at it) and my anger (stubborn as well). My boyfriend also is stubborn and has anger issues. Lately we have been fighting a lot because of the stress and with added anger issues, it makes it worse.
Though we have talked about going into couple counseling and anger management. We haven't yet because we don't have the money right now and he's going to counseling for other issues he has. I am trying to get a second job to help with the money issue, so I hope soon we can go.
