It never actually got that far but I think DP and I got close a few years ago.
DD started comp just as COVID hit, so was in year 9 when all the restrictions properly lifted. Suddenly she was out all the time with her mates, making up for lost time. And we kind of did the same, as suddenly we had a lot more free time, and no restrictions.
We both started new hobbies, separately, and saw our friends separately. Even at home we tended to do our own stuff, I think we'd just got so sick of watching TV together through lockdown.
After about a year of this, we kind of lost the ability to talk to each other properly. Not about important stuff or logistics or DD, but just the usual chit chat of our days.
Luckily, we had a few days away booked in, for a gig that had been cancelled during COVID. We went, and both realised how much we enjoyed each others company, and how much we missed each other. We started making proper time together after that, and it fixed things.
But I do wonder if it wasn't for that gig, what would have happened. Would there have been something else to act as that jump-start, or would inertia just have kept dragging us in opposite directions until there was no relationship left.
