even if I wasn't in a long term relationship at the moment, no, I don't think I could do a long distance / online relationship. I don't have any plans of packing up and making a massive move, and I wouldn't want someone to do that for me again, either. For me, if neither party plans on relocating, then there's just not much point to pursuing a relationship.
I did date a few people through forums in my teenage years, though. Even got catfished through Tumblr when I was like nineteen LMAO. I met a guy on a dating app in my early 20s who only lived 3 hours away, and we dated for a year long distance. I hated it - I don't like driving that far, and sometimes it feels good to just come home to your significant other. Once he finally moved up here, I realized that I wasn't as in love with him as I was with the thought of being with him. He was just a really different person over text message/IM versus IRL. We wound up dating for another 10 months after he moved up here, but we eventually went our separate ways.
With my current relationship, we lived an hour apart for a long time, and even that felt kind of like a long distance relationship because we worked literal opposite schedules (Me: 8AM - 5PM ; Him: 4PM - 11PM). We eventually wound up accidentally living together and it just kinda worked out lol
