Just because I'm not in a relationship yet after being separated for 2 years,my ex thinks I've not moved on! I thought it was about finding happiness within first before committing 2 anwother person.my ex jumped into a relationship and his telling my son he's depressed! Would someone be able 2 tell me what they class as moving on?

1. Getting into another relationship and NOT missing the last relationship enough to want go back to it. Even though it doesn't sound much like moving on when you get yourself into another bad relationship.
2. Not getting into another relationship but doing like you did and make your own life the way you want it. A fulfilling life because you learn to be yourself and independent.

You both have your own way of dealing with moving on. It doesn't take another relationship to get over the past to be able to move on. If you are still wanting him back or living in the past with spite or negative feelings then NO you haven't moved on.
