How to move on from someone you really like but doesnt like you anymore?

hey! 22 (f) here, so I’m trying to move on from someone who seemed pretty into me and wanted to date me to now not even having the headspace to talk to me. I’d like to give some context here. We matched on Hinge back in February of this year, at the time I was in a FWB situation with someone else which wasn’t serving me well but I had just started talking to this guy. He seemed pretty fun and very into me since the beginning but I was trying to take it slow. because of him not being in the city and me having strict parents (I’m from India) we didn’t meet up till June but spoke regularly and he flirted with me all the time, I asked him what he was looking for and he said he was looking for something serious. Look now I’ve been heartbroken many times by liking someone and them not liking me back or just not being into me enough to date me and while I have moved on from it, it still stings and it’s not a very nice situation to be in so I had repeatedly asked for reassurance from him (not way too many times just occasionally) We had our first proper date in July, we met at his place, he got me flowers, drinks and snacks and overall made me feel very comfortable and during this time we discussed too that we’re not wasting each other’s time and we both had a really nice time. now after this, i planned something and he fell severely sick so I just gone to see him and he said i promise to make it up to you, we’ll do something fun soon. He gets better and goes back home for a while since he has work, we’re still texting at this point but his replies get fairly slow which i know happens when he goes back home but they had gotten v v v slow like he took days to reply which i didn’t attack him about but I just asked him if this was something he still wanted to do and how it was making me anxious. he knows all about my mental health issues and my anxiety being the worst of them all, he reassured me we’re going with the flow, I’m really busy rn but I promise we’ll figure it out don’t overthink about it. slowly his replies got slow to a point he kinda stopped replying, i asked him once what is up and hope you’re well i can image u have a lot going on but i’d like to know what is up. to which he sends me a whole message saying he is overwhelmed with work and doesn’t have the time for anything and a bunch of things which i respect and again tells me dont overthink about it. he says he wants to keep the conversation light which i tried to for a while but i really like him at this point and just wanted to talk and realised this was not working for me and sent him a long message on how i wanted to kind of end things. he says he needs time to respond to it but doesnt respond. i message him again saying a bunch of things about how i miss him and idk what i did for him to hate me and he says im so busy I don’t even have the time to think about u, i’d like to mention, i am a veru understanding person in all my relationships and i know most of you will think why did i just not stop talking to him but this guy promised me repeatedly that he wont break my heart and that i was safe with him. cut to last month’s end he asked if i wanted to meet in person to sort this out and i get very excited because ofc i thought he wanted to make amends but i figured out that he just wants to hook up which would be okay if he had made it clear in the very beginning but at this point i had feelings for him and he didnt seem to respect me anymore or so i felt so i kinda got angry and told me lets not talk anymore and that it really hurts me to try and talk to anyone who doesnt even think og me to which he said I’ve tried telling you so many times im not in the headspace for anything rn and i just tell him a bunch of things like you wont hear from me again and that i wont bother and all. Ik he is not the problem here, i just want to move on cause it really hurts to like someone who seemed to like you and promise you things and now is just acting like this.
