I'm going to tell my gf to leave
Why do you want your girlfriend to leave you?
She hasn't tried to change and I haven't felt close to her in awhile. We don't get along anymore.
Breaking up can be tough to go through. If you truly feel that you are no longer in love with them, then it would be disingenuous to continue the relationship. Try to be gentle and empathetic when telling your partner about your feelings.
I feel good about it. It's about time I end the relationship. I want out of everything.
It's normal to want to cut all ties in a relationship when you have drifted apart. It may be hard for her if she doesn't feel the same distance.
