Do you honestly lack the aptitude to think for yourself in such an easy matter? Support? For crying out loud she's the one with the kid, with a violent ex, depressed and on medication, possibly having an alcohol problem with no job and you're thankful for support on if you should stay with a crazy lady or not.
Wake up, it's a no brainer, if you don't like something and have the option for it to stop, stop it. It's fruitless to go on when you don't want to or see problems.
You needed us to tell you that.
Chris, this is all part of Aspergers Syndrome. An inability to see the world from someone elses perspective. Not everyone has the luxery of understanding the world like we do. Maybe in future you may choose not to be so judgemental and patronising!
