Need boy help

So, I 23F need some insight to maybe what this guy 21M whom I’ve been on and off with issue is.

I met this guy off a dating site around April, and we went on an amazing date. Urbex exploring & car meet. Hit it off and then we slept together our second date and ended up sleeping together a lot over the next month & a half . Halfway through i asked him what he was looking for, and he said just friends w benefits. He knew I was upset but I said okay I’ll try, as I never have done that. So moving on we keep hanging and I even stayed at his place for a week straight and it was an amazing time. After that week , I realized it was hurting me too much because I just wanted him and I texted him saying I couldn’t do it and unadded him. A month goes by then I re add, and reconnect w him and we hit it off and talk about how we miss what we had . We Make plans to meet , then the night before our plans he blocks me while I’m asleep, after he sends a text saying “I’m sorry I can’t do friends with benefits, it’s not you don’t worry it’s just me.” I even reached out on insta the moment I woke up, he saw my text & blocked. Okay.. so I move on and a month later (A few days ago) he re adds me on Snapchat. He says hey, I said hi and he just is casual and says how have you been and we start chatting but his responses get slower and slower. He says he wants to see me again. I jokingly say “well why’d you block me🙄” and he said he was going through some things . We make plans LAST NIGHT to hang this weekend for a couple hrs to.. yknow have fun . He said okay, he’ll let me know when he’s free to this weekend. I wake up this morning and I’m blocked again.

Please I just need some type of.. closure or understanding on WHY he’s doing this. What could possible be going through his head. Is he trying to push himself away from me bc he likes me but is moving out of state next year? Or am I just someone he can easily sext and make plans w then block I don’t get it . I really like this guy, I haven’t been able to connect with anyone else since I’ve met him. I just want him so bad and it hurts going back and fourth. I feel stupid and this just brought back all the hurt I thought I moved on from. I wish he wanted me but maybe he doesn’t ? Idk. I need insight .
