I'm still in love of my ex, is it right that I made him hate me?
Why would you make him hate you?
So that he will think of me all the time.
It sounds like you are confusing love and hate. Once a relationship has ended, both parties are expected to move on in life.
I know what I'm doing and I'm going to make it work.
The way you're going about doing things, I don't think it's gonna work out at all. If you want to get back together with them, making him hate you isn't gonna make that happen. You should be upfront and honest with your feelings.
