>going to con with gf in a couple months
>Girl I used to talk to and was head over heels for before current gf is going and wants to meet up with me
>Feel like I'm slowly falling out of love with my current gf and I'm starting to avoid talking to her via call (it's long distance)
I'd never cheat on her but I worry that things are just... Ending. That things are over and I'm just prolonging a relationship that I no longer feel a genuine desire to continue, but rather I continue it because I can't remember anything before it anymore, and that scares me. I worry if I end things I'll develop that spark again or passion and I'll have lost her.
