I need help!!!

So I’m in high school and I’ve had like my first love who hurt me last year, I’m over it tho, but I kinda ignored love and the idea of a relationship until this year.

So I met this guy through a mutual friend and we instantly hit it off...he just came out of a serious relationship and I officially ended things with an ex so we were both pretty sensitive at the time.

We talked a loooot and in no time we were saying I love you and all that serious stuff.

So literally three days after we had a really I guess you could say flirty conversation he gets back together with the girl from his previous relationship THAT CHEATED ON HIM and I cried for two days straight and got drunk at a friend’s house. Like I said, I have trouble opening up and when I do and it blows up in my face, I do stupid stuff and shut down.

Fast forward barely two weeks and they break up again. He called me and we talked casually for a while and then it got really heavy flirty but cute not sexual or anything which really messed with me.

Everything was great until a few weeks later he barely calls it off and moves onto another girl and friend zones me hard.

Lather rinse repeat about another two times and then this week I decided I’m over it. I’m just emotionally drained and it sucks because he is my best friend but he played me damn well.

So he’s very deliberate when it comes to saying certain things or sending pics or whatever...and today I was looking pretty decent so I wanted to play him a bit. I sent him a kinda nice pic ig and then it got flirty real fast. But yeah no feelings.

Later today he was like tms and I told him that it’s cold and he was like come here...I replied with cuddles? And he thought he friend zoned me by saying: do friends cuddle?

I cuddle with all my friends so I told him that and then I asked him why he was being weird bc it is. He said he doesn’t wanna mislead me (now all of a sudden) and Idk if this was a boss bitch moment but it felt like one so I said: you know I’m over it right it doesn’t matter anymore so you don’t have to say weird stuff to make it awkward.

And now it’s hella awkward which sucks because once again he’s my best friend and I really miss him....

Advice???
