I'm going to break up and kick my depressed gf out
Why would you do that to her?
Because she has been badmouthing me.
It is wrong to kick your girlfriend out of the house and break up with her if she is feeling depressed. The first step would be to try and help her get some help for her depression before kicking her to the curb. If you still dont want to be in a relationship after you give her some help then you can feel free to break things off.
Don't worry, I can always find another girl.
That's not what I'm worried about, I'm saying that you shouldn't just kick your girlfriend out because she's depressed. You need to get her some help instead.
