I feel like I love her and hate her.
What's the reason you love her and hate her at the same time?
I miss her so much after she left me.
We can't control whether people want to stay in our lives or not. As unfortunate as it may sound, you just have to accept things as they are and move on.
Don't tell me what to do.
I'm just offering you practical advice on how to move on, not demanding anything from you.
