i tend to only be infatuated with one person at a time, but sometimes i'll be infatuated with multiple people. levels of severity vary.
i was infatuated with my ex-girlfriend for quite a while, even when her and i were still together. she was "my person". when her and i broke up for the last time at the end of september, i lost my shit. then, after she blocked me on halloween, it got way, way worse. i was constantly thinking about her until the end of december. the worst part was that i'd have sexual fantasies about her. i still feel gross because of that. now that it's been almost 4 months, though, i've started to let go. it's really fucking hard, but i know it's for the best. i've met a lot of new people since, and even when me and my ex were still "friends" i was talking to a handful of them.
being infatuated with her prevented me from having more than a few acquaintances. i was wholly obsessed with her to the point where i didn't focus on anyone i had a platonic relationship with. looking back, i can't believe that i'd sit there and wonder why people would come and go so quickly. being single has given me the glorious abilities to 1. hook up with however many/whoever i want and 2. have a huge circle of friends and spend all my time with them. it's so much better.
