AITA for wanting a relationship after a year?

This is gonna be a long one so bare with me. I (20F) have known this guy for about 13 months we met on a dating app and started chatting. We were just texting everyday for about 6 months,we talked about meeting up but we were both very busy with me starting college and him getting a new job, we werent rushing to meet up it was winter at that and we both just wanted to get to know eachother better. After the 6 months he started to not really answer back could be like a whole day, i asked why he isn't answering and if he doesn't want to talk anymore. He said that was not the case an he was just busy, to make a long story short he ghosted me. After 2 months i still couldnt really forget about him and because he never really told me that he doesn't like me i just couldn't get over it. So i wanted a clear answer, i texted him that i miss our texting thinking he won't answer back or say he doesn't like me, but low and behold he said he misse me too. So we started chatting again and finally met up, he was so nice and he seemed to like me back. We went on another 5 dates. On the fifth date things got steamy and on the sixth one he took my virginity. So i thought that meant we would start being official, because at that time we've been seeing eachother atleast once a week for a month. A week later i brought it up if he wants to get into a relationship because i dont want this to end as a friends with benefits. He said he wanted to wait a one more month before asking me to get us to know eachother better, at that point we knew other for about 10 months if i don't count the 2 months we didn't talk and it was 2 and half months since we met for the first time and i have slept over at his place already. We talked about it and and he asked if i want to get together i said yes but i dont to get together through messeges. Which i thought meant he'd asked me when we would meet up the next time. That didn't happen so i thought he wants to wait some more which i was fine with. Another month passed, i slept over at his place every week and we went together on a trip over night to another city for a exotic pets showing. Everything seemed well we were intimate a he was really nice and i had a lot of fun spending my time with him, we texted daily. But ever since the trip he has been acting differently. Already when we got on the train that day to get there he seemed a little off, i just thought it was because he was tired after the whole week as it was friday. When we got back he started to feel distant less texting, not really asking how i am, it just felt off. I am quite insecure and i thought he got bored of me or i did something which made him not really want to talk to me. I asked if i made him mad somehow on the trip as to why he hasn't been really texting as he used to. He said it was nothing, this has gone on for a week, which made really anxious i was stressed waiting for him to answer as it could take him hours to get back to me i thought i was loosing him. So i asked if he still wants to get in a relationship as its been a over a month and nothing changed he said he doesn't want to talk about over texts and we would talk about the next time we meet ( we haven't seen eachother after the trip for about 10 days as he got sick ). This didn't really help i understood but i was still anxious. Few days later i just couldn't take and i asked if he truly cared for me because he felt distant as he was texting a lot less and i just needed some reasurance that everything was alright, because i cared for him and didn't want to lose him. He responded pretty irritated that keep asking him and that its annoying. That didn't help at all. After few days i slept over at his place he felt somewhat distant even in person, he was touching me less when we were laying on bed, he talked less and played videos he wanted to watch didn't even ask me if i wanted to watch them. In the morning i just couldn't take it and i asked him about our relationship because he didn't bring it up, if he wants to be with me or not, he said he still wants to wait some more to be 100% sure. I said i dont really feel comfortable in this situationship and that i want some reasurance, he said he cares for me and that's why he wants to wait. I said i'd wait but only till the end of the year if he won't be sure by then i don't think this has a future. Later that day he texted me that he feels like i am rushing him into a relationship, i've never been in a relationship he was my first everything, but dont know how much better he wants to get to know me when we've known eachother for such a long time now. Because now i just feel like hes using me waiting if someone better comes. I try not to overthink it but it just feels off i do think i love him and i truly care for him but this situation is hurting me as i feel he doesn't take it as seriously as i do. I don't know what to do.
