am i overreacting if i end a friendship over being rejected?

i (20) have been friends with someone (also 20) i met off hinge for about 9 months and it hasn’t always been a good friendship as they would ignore me for days on end and i always had to start conversations, brush me off/ make excuses when i tried to hang out with them,etc. but after that i told them how i felt and they apologized and promised to do better and they had been. at first our relationship was platonic on both ends and this person had always made it clear that they had no interest in relationships and they had a hard time developing crushes on people and that relationships had no importance to them. (which why were you on hinge in the first place but whatever lol) fast forward to a couple months ago we had been getting closer, talking almost every day,going out to eat together, we went to a concert together out of town and i admittedly developed feelings for them. so last week i told them i had feelings for them and they told me they didn’t feel the same, which was upsetting of course, (but it was expected with everything they had been saying abt their disdain for relationships but i thought why not shoot my shot?)and they tried to make me feel better by telling me that they never really have had a crush on anyone before, which did not make me feel better at all lol. so i told them i’m just gonna take a few days and feel what im feeling and try to move on and they said that they would be there for me if i wanted to still be friends with them after that. so like a day or so after the fact i think ‘why not redownload hinge and see who they have on there’ trying to take my mind off of being rejected. and LO AND BEHOLD the friend that i got rejected by IS ON HINGEEEEEEE 😭 and that just added insult to injury honestly. but also why would they feel the need to lie abt not wanting/needing to be in a relationship?!? and honestly after that i don’t know if i really want to talk to them anymore. i feel like it would have hurt less if they had just said that i wasn’t their type or something instead of spinning this whole thing about not wanting romance 😭 am i overreacting?

TLDR; my friend who had always talked about how unimportant relationships are to them rejected me but i saw their profile on a dating app the day after.
