Is he not interested?

So I hung out with my new crush the other night for the first time, yes we had sex but it was only for 3 seconds because the condom came off of his dick and got stuck in me. He joked about it saying “bloopers” but then I was embarrassed and he was telling me not to be. Anyways, he was so sweet and perfect and caring and loving when we were hanging out and I could really feel myself falling for him, but ever since he’s been dry over text or hasn’t text back at all and it’s been 3 days so I addressed the issue and asked him if all he wanted to be was fuck buddies and he said that wasn’t the case but that he wanted to see me again but when I told him I was in my bed he never replied. So it makes me feel like he’s just trying to fuck because the only time he really text me is when he wants to see me. Other than that he sucks at texting and takes hours in between messages. And its not that he’s busy because he’s on instagram and other apps, he’s just not replying to me. I don’t know if I should continue to put up with this because I really did start to like him or if I should just leave it alone and ignore him..... is he just not interested?
