This actually has helped me, especially the treating me better part. Certainly makes it easier to believe that I am worthwhile.Not very many people recommend it, but I think that finding a temporary person to rebound with is a great way to take your mind off of your ex.
The problem is, you still have mental and emotional attachments with your ex. The goal is to detach yourself from him. Finding someone else who cares about you and will treat you better. Dating doesn't have to be a chore. Try to have fun.
