I just cried for a girl?

i kinda like this girl. I'm a ******* manly type of guy and it's really hard to get into my heart. I was listening to this one song ( it was really gay-ish Chris brown next to you) and it just kind of made think bout my girl. To my surprise tears started filling my eyes? Is this normal for a person like me? Is this love I don't understand it? I don't to all these gay songs. What is wrong with me I dont want this to happen to me again. I'm a man. I rarely cry!
