What do you think? I am so confused

I am 16 I just got out of a relationship. I was with this guy for 1.5 years. And he always liked to touch me, weather his hand was on my knee, around my waist, over my shoulders, we were holding hands, whatever and he always loved that. But about the last month we were dating he got a lot more sexual! He put his hand further up my thigh, he put his hand lower on my waist, we wanted to give me more hickeys, he wanted to make out more. So a few days before he dumped me, we were on his bed and we just finished watching a movie (we were home alone) as the credits roll up he looks over at me and then smiles. He leans in and kisses me, the kiss is slow, gentle and long. After he pulls away we smile at each other and he starts to kiss my neck. He found the “sweet spot” on my neck and my head fell back, I looked over and I saw a condom on his night stand. He pulls away from my neck and takes his shirt off and then clearly wants me to do the same. I then explain to him that I don’t want to have sex, (I am a virgin) and that we maybe can in the future but definitely not right now. He said it was ok but he was clearly frustrated. A few days later he wants to meet up with me at the park, in his whole breakup speech he explains how I don’t love him anymore. I then look at him annoyed and say “is this because I wouldn’t have sex with you” he then looks down at the ground (he is visibly more upset) and says “whatever we’re done anyway” and walks away.

Did my boyfriend just dump me because I didn’t want to have sex??? Please comment what you think about the whole situation, I honestly have no idea what to think.
