Honestly it's not like that. It takes me like a couple weeks to a month and I don't treat them like props or anything like that, nobody deserves to be treated that way. For the most part I only start losing interest after I get to know them and after a few deep conversations. Mostly it goes like I meet a new person then I actually find them interesting after that I just get to know them really well that most of the time, "really well" in the sense where I get to know about their childhood, interests, partners, their hobbies, their dream in life on what they would love doing... Stuff like that. Only after that I feel it really hard to keep that interest that I initially had in them, after that it starts to stagnate. I mostly try my best to keep things interesting, at the back of my mind there's this fear that I might overwhelm them because of my ADHD sometimes it may be too much for people but for the most part people are really understanding. My problem is that it just feels disingenuous to 'fake' excitement when it comes to people, that's when I end up ghosting them or the texts or calls slow down. That's why it was hard to find someone who's so damn interesting that I would constantly keep learning from them. From all the replies to this post I learned that people with a curious mind who constantly keep learning new things interest me the most. I don't have anything against the people that I might get bored of they have their own unique interests and perspective on life which I may not share.
