So sorry you're struggling. It sounds like you broke it off with him for a reason, which was very valid. It is common to then remember all the good times and forget about the reasons you broke it off. It sounds like he is very outgoing, which may be overwhelming for you. That is not likely to change.

I agree with Divine that you have your whole life in front of you. Don't let one jerk on a date scare you. There are lot's of great men out there, but you do have to weed through the bad one's. My friend told me that dating is a contact sport!

I have had a similar experience recently where I broke it off with a man that I fell in love with. Neither of us were ready to move forward. But now all I can think about are the good times. I have to remember and remind myself daily why I made the decision and why he isn't right for me. It is a process. (((HUGS))).
