I feel like a toy in a relationship. My gf wants to break off yet still insists that we stay together
Why do you feel like a toy?
The relationship was built upon false expectations and I don't want to be it's toy anymore.
It seems that you don't feel respected or appreciated in your relationship. You should talk to your girlfriend about how you are feeling and be sure to have boundaries so that your girlfriend will know where you stand.
I hate her for saying that and lying about what she did to me. I hate dating.
You should tell her how you feel about the relationship. If nothing changes at all, then you should break it off with her, despite her protests.
