Let me start this by saying, ive been in this same position a million times, with like a million different guys. this isnt a special case, its a repeating pattern. 

I found this boy i reeeealllly liked, got him interested in me, and i was having a good time with him; that is, until he started getting blatantly romantic with me. 
yesterday the rose tinted glasses came off the second he kissed me. it was an instant change. 
i used to want to text him goodmorning, and talk all day, but now he feels almost dead to me. i dont want to talk to him, or hear from him, or do just about anything with him. this is all because of one kiss.
so my question is: what the hell? how did he go from my dream boy to the biggest ick ever from just kissing me?

this has happened to me with every male relationship i have ever had.
i can obsess over a man and be so infatuated with them until they return the favor and start being romantic.
this is like the eighth time this has happened to me. what the hell?
