My 2 year situationship blocked me out of no where

I (26F) am feeling very anxious about my situationship (23M) blocking me. This isn't the first time. The first time was about a year ago and I was so disappointed that it made me sick. but 3 months later he came back. I made him try a little but probably not enough and we see each other probably every other week sometimes more. He has made it known to me that he is not ready for a relationship and I get that but I still love to see him. Recently, he calls me every time he is drinking and tells me how great I am and how if he was smart he would be with me, and then other times he is like, "you are so obsessed with me, its too easy". So I am left feeling so confused. If I talk to him about it he shuts down and won't tlak to me about it and just says nothing at all.

I guess I am just wondering what he is thinking from a guys perspective? I truly feel like when we are together we enjoy each other so much but when we are apart he doesn't want to hear from me and ignores me unless he initiates the conversation.

He recently blocked me a day after hanging out but added me back 2 days later- invited me over- then unfriended me when I left his house and haven't heard from him since. That was a week ago.

Typically, I overreact and over think and try to talk to him when he blocks me and this time I have not. I just can't help but wonder what he is thinking and if he will recognize my absence and want to see me?

He does work out of town a lot and has a lot of friends and brothers so he is never not busy.

I truly care for this boy and I know there are other guys out there but Idk I truly can't throw away a connection like that... and it makes my stomach hurt to think he would. Any advice?
