Haven't really ever fallen out of love with a bike. One time long ago I learned about weight transfer and front brake efficiency when stopping at the bottom of a step drive. Went over the handlebars with no helmet. I was sore, stiff and scraped up, but got back in the saddle within a week. Because it was operator error I liked the bike as much afterward as before the flip.

My recommendation would be to visit a physical therapist for that finger if you haven't and consider getting back on the bike. You put a lot of time and love into restoring that lovely vintage 2 wheeler and it really should be enjoyed for what it is. The forgiving should be for yourself and not the bike. You may find that your feelings about the event change a lot after some time spinning those pedals.
