as an infp, do you get attached easily?

I’m not even exaggerating when i say this.. I met this guy once (not even in person btw) and immediately got attached. it happens so often, i make up conversations in our head, i make out entire scenarios specifically with this person. im 100% certain this person hasn’t thought of me any further which is the gut punch! But, ive also noticed that i get attached to things that i own. I mean obviously one is inclined to feel a deeper emotion to something they OWN, but i can’t ever get rid of anything. I’m too scared. I know im not alone in this feeling.. i can’t be crazy LOL.
