same, I have a couple that have been going that long pretty consistently consistently too and I hope they never drop me XD I mean one is with my gf so she's stuck with me for a while yet!
Started a Anita Blake OC RP way back in like 2002, and it last till 2018 when I had a falling out with the person, due to trusting to move in with them after being friends online for so long. Big mistake on my part. But if you mean on here YD, 2014, a Naruto Akatsuki AU, and still going strong with it. My RP partner is amazing <3
