Hi @mell79
There are things we cannot change about others. Experience has shown me that each person changes, because they decide so. Thank God and life that you didn't waste more time with your ex, because obviously, he couldn't give what he didn't have: Love. By lying, people show that they don't love themselves, and then, how can they love others?
Just take the beauty of that relationship, and also what you have learned from your time with him.
A big greeting.
