I really dislike my ex dating someone new, It makes me so mad!
Why are you mad at your ex for that?
I wouldn't care who my ex are dating just as long as I see her.
I get it, but you shouldn't even be concerned about your ex. You should just move on from her.
I can't move on until I talk to her.
I think it would be better for you to move on. If you keep living in the past it might cause you a lot of mental anguish.
