We met on OkCupid.
Some things that helped us to have fun experiences dating for so long without being nearby, if you’re looking for ideas:
Skype on both desktop and phone allowed us to talk both at home and share walks / time outside. Super super long Skype conversations multiple times a week.
Tabletop Simulator on Steam if you like board games
Movie sharing through Teleparty and Amazon Prime
I know you’re not religious, but we “attended” the same church livestreams and talked about them during and after, which was awesome. You could sub in any other kind of thing like a Ted talk or a podcast you’d both be interested in.
Also had two “book clubs” going that were just the two of us (Bible and non-Bible)
