I (f17) feel NOTHING after breaking up with my bf (m18) of two and a half years

We've been in a serious relationship for pretty long, i truly believed that we'd be high school sweethearts and get married but here we are lol. Everything started going south when he left for college. He started lying to me 'to avoid conflict', he wouldn't share enough information with me about his day which led to me feeling uneasy, he started calling me names and becoming very disrespectful towards me, he started liking weird reels that he knows i would feel weird over (like gym girls and videos very obviously negatively targeted towards ME) and we got into lots of arguments that were mainly coming from me because of shit he did. For example, the very last big fight we got into was because he didn't update me for a long time on what was going on with him cause he was giving me the silent treatment for posting myself on my GIRL ONLY PRIVATE ACCOUNT. Anyways, when he finally told me what he was doing the entire time he didn't talk to me, turns out he went out with a friend and he went to an event thats known for being very touchy touchy between the men and women. They started talking about how the women looked and stuff. Afterwards, they went out to dinner and had a conversation about weird things that I don't really wanna talk about lol. Anyways, I started telling him that Im disappointed and how hurt I felt about everything that happened, and out of a sudden HE'S the victim. He started telling me that all I've done these past few weeks was complain and argue with him and how ungrateful I've been. I apologized and he hung up on me. He then ignored me for DAYS, and each time I called he'd call me names and make me feel embarrassed and sad that I even reached out. It just got to a specific point where I genuinely felt rage that I kept reaching out and he just kept making me feel this way. Right before the last time we talked, I found the weird reels he liked which sparked a bit of anger in me, and then he finished it off by the lame excuse he gave me. I called him afterwards and he just did what he had been doing for the previous couple of days. He hung up on me, and I just sat there thinking to myself that I hated him. Out of nowhere I sent him a message then blocked him everywhere. Its been a day since, and I haven't shed a SINGLE tear. This is soooo weird to me since I've literally been crying over our relationship for weeks. Its gotten to the point where I went back to an old addiction to try to cope with the sadness I felt from him. Now that I've ended things, I feel absolutely nothing. Will it kick in at some point? Or is this it... Was being in a relationship with him MORE HURTING then NOT being in one with him?! That's so crazy to me!! What do I do now?? What's my next step?
