Why do hot men deal with rejection so poorly?

So… There’s this guy I dated and he treated me the way as if he wanted something casual, so when I met up him I told him I used him for forgetting the guy who I had feelings for long distance and that I dated him because my leg was broken and I wanted to prove myself that I can still have anyone I want, even with just one leg :) His face changed and I can tell his ego was hugely hurt, he is probably used to be the one using people. He told me I am a hypocrite because I treat people this way and don’t like or accept to be treated the same way. I said, I am indeed a hypocrite. And that I will not accept other people play with me the way I like to be the one playing.
Then I gave him the best kiss as a goodbye, he’s been texting me to meet him again, I haven’t responded for a week and now I sent him a break it off text, he was upset and told me he is not looking for something casual with me and he wants to treat me better and take things more seriously. He also said he is willing to wait for sex as long as it takes for me to feel comfortable.
Isn’t it a bit too late? Why do guys start pursuing you after you reject them?

Also, we haven’t had anything sexual. I just kissed him.
