Why do you love the one you love?

i dont know what makes us click we juss go together 4 some reason but im not sure what it is! i mean but i dont know how long it will last he is a freakin cheater ( or so his friend says )

I love him because he understand me and he is the first person to listen to my problems,plus we have alot in common.Plus he's very loyal to me and when I cry he comforts me.
