I'm reminded of the time Facebook prompted me to "reconnect" with my beautiful wife, because we hadn't communicated in some time. Ah, no, we just don't communicate with each other via Facebook.
Sadly, most of my historic data (we've been together 11 years; married 6) is lost in ancient phones. One difference I believe we would observe compared with the OP is how prominent xxx would appear (representing kisses, I might add). We made a tacit agreement early in our relationship to always add those and/or an expression of love at the end of messages and conversations. One of those little things that can get lost in transactional stuff, so I'm glad we made the effort (even if it's now mostly habit, it's still valuable).
