My first relationship ever

So guys about 4 months ago, my friend introduced me to this guy , and he came to me first and he was like I like u , I used to see the stories and I had a long term crush on u , and so on , any ways like in July , we got together like in a relationship, and it didn’t last a week
But what hurts me the most is that he kissed on the lips and that definitely was my first me and he touched my body, and I didn’t want him to I just was to scared to tell him that I don’t want that , the thing is after that like in 2-3 days I don’t remember exactly, he texted me that he can’t be in a relationship and he loves but he can’t be the boyfriend I deserve and things like this ,
He broke up with his ex a year ago and she was his first love and she cheated on him after 4 years together, and when it was to late I realized that he is not over her and he is not over the fact that he got cheated on, the thing is now I feel like I was the rebound, because even when we broke up we still talked everyday , and I begged him to try again a billion times and he refused, but the last time I asked him to try again and he refused, I blocked him, because I don’t deserve this .
I feel like a total rebound especially that he didn’t even tried to text me , we haven’t talked in 3 days now , and still zero messages from him , it’s sad because we used to talk everyday, and extra information I feel used and not clean after what he did to me , I’m muslim and all this is haram , I feel guilty because I’ve never thought I would be here . I wish I could go back in time and never let him touch me .
What do I do now ?!
Will he come back?!
