Definitely! Attachment was the main problem I think. Attachment requires a confluence of a lot of happy emotions at high levels and in connection with a specific person. Happy emotions yes, but not at high enough levels I think.

For the record, after I wrote my last post I realized I had never actually asked him if my best guess of why he ended it was accurate. According to him, mostly accurate but my low conscientiousness was less of a factor then I assumed, but low energy was a factor in terms of me wanting to do things with our mutual friends and him not wanting to.
