Opposites do attract, that sure sums up my relationship. If you have a desire to be more outgoing, what can you do about that? There are books that teach how to be more assertive, there are groups, like toast masters to practice those skills. Lots of people overcome shyness, so can you.

What contact tends to do is push us back instead of forward. Maybe look into a dog kenneling service?
You can pick people that you admire to study, how do they do it and how you can be more like them. I've been reading biographies lately of people I admire. Good stuff! My ex is charming and outgoing but it's an act, it's not sincere. Not something I want to learn.
