Its definitely not the norm. In both of my situations we found a connection i started going on dates then we started traveling together non transactionally. Both had trouble accessing the banking system so i was co-signing car loans and apartment leases, putting them as authorized users on my credit card etc

Took a lot of communication to pull it off.

I also found both relationships to be very enjoyable which is one of the reasons i get the urge to go back and reach out but i know that deep down that will ruin the memories.
