Is it normal to go all the way for the one you love?

It is absolutely crazy how far you can go for someone you love. Obviously, if you weren't into that person at first, you're not gonna go all the way. So this is the first time I ever caught deep feelings for someone and now I'm going through the break up and it is the sh*ttiest thing ever. Like you put everything into it, you let yourself go even to an embarrassing extent. Last night was just something I would never do as a person but like I said, when you're crazy about someone you will go all the way until you have nothing left.I was waiting for a text from him to meet up and express ourselves and say bye. I went out, tried to enjoy the night, knowing it was going to end bad but didn't really know what to expect especially that I was going to drink. I planned on not drinking a lot so I can prevent a lot from happening but even with a little (ok I drank more than I planned to) the tears came running down like a waterfall because he never contacted me. It was crazy how I couldn't stop them and I was with a group of people and my friend and they all saw me crying. I was just like ya um bf problems. I ended up going home calling him a million times, no answer nada. Then I decided to call his roommates like a clingy, crazy gf would do. He texted me saying "I'm asleep." Like no you just don't want to see me so just tell me. It was just yet another cherry on top to how he doesn't want anything to do with me. What I'm sobbing over is why can he grow the balls and tell me that? Every time I ask him to chill, he says ok, but doesn't do anything about it. I grew the balls to text him if it was fine to see each other and he said okay thats kool when he could have said no I don't want to see you and I would've been relieved to hear where he stands and just left him alone. I think most guys say "okay" most of the time because they want you to stay so you're there when they want or need you. They rather feel secure that you're still there. It's a really mind-f*cking thing to do. This whole thing though is like Coldplay's "Sky full of Stars." Where he sings,"I'm gonna give you my heart, idc if you wanna tear me apart...and idc if you do." Yup, I've given him everything as much as he has destroyed me. I still keep going and giving him chances. Its just in me and idk how to stop it.
