I'm afraid I really hate my girlfriend sometimes
What is causing you to feel you hate your girflriend?
I am getting bored with her and beginning to feel annoyed when she talks about all the things she does.
If you are not feeling like you are in a positive relationship, it may be good to talk about it with your partner. If this is something that can not be changed, then you are better off getting out of the relationship for your sanity.
But I love my girlfriend and I don't want to let her go. It's only sometimes that I hate her.
Even if it's only sometimes that you hate her, it's still better that you break up with her because these feelings you have are toxic.
