<human>: Can you succinctly summarize the text in 1-3 sentences?

Me and my boyfriend met on tinder about 6 months ago, and started dating 5 months back, and been more 'officially'/publicly dating since October. Things have been going well, and he's met a few of my friends, though I haven't met any of his yet. We're at the point where we're discussing meeting each others families.

Anyway, one of my friends signed up to tinder this week, and wanted to see what my profile had been like when I was on it, so I logged in, and decided for the hell of it to check my boyfriend's profile. Which said he was last active 1 hour prior. I checked again today, just to confirm my doubts, and once again, he'd been active only a few hours before.

I don't know how to bring this up with him, as I'm really awkward with romance, and he's my first official boyfriend. Any help is appreciated.
