Nice one! Sounds like you've got a pretty good wingman, a good mentality of abundance and making it fun for yourselves with the competition thing going on. 15 approaches is quite a lot so much respect and it's always nice to suprise an ex with how much you have progressed and moved on.

I wouldn't worry too much about the lack of following through as it seemed like you were just trying to do as many approaches as possible and this is a good way of getting rid of any anxiety. So the next step is to follow through and show some interest and intent. The good news is you've got past one of the main obstacles and you have approaching nailed.
