wouldn’t participant in them myself unless i was in a long term relationship for over half a year before one of us moved away and they were less than a 4 hour flight away with a plan to eventually live near each other after a year or two. Any more than that and it’s a “when I’m done with x and can relocate if we are still single let’s talk about picking this back up”
I absolutely wish I could make them work so I could be with this girl I’ve had a mutual crush on for a whole year (it pains me that she is so far now), however to really make them work I’d need to be in a secure relationship prior to moving to a LDR and have plans to reunite someday and be close together again
