I can't seem to get over my first love?

[Bianca]

its just hard,
you know, its crazy how you can be so in love with someone, its insane.
its like, he is overshadowing my life, and happiness.
I was currently in a relationship with this other guy, but dating him made me
realize that im not over my ex. so I broke things off.
I just need a reason why he cheated on me, he always told me that I was the one.
that he never found a girl like me before, and that he will never hurt me.
but the stuff that he did, and tried to keep it a secret, shattered me.
i trusted him, and he did this to me, i am really emotionally damaged.
he has me as a friend on facebook, and I go to his page all the time.
he was currently in a relationship with this other girl, who i guess made him happy.
its been more 7 months. hearing his name always makes me go weak.
and depressed. our first kiss, was special. and I do think about that all the time.
he always messages my sister. but he cant message me?
i really miss him, and its ironic of how much of a impact he put on my life.

so my question is.. do you ever really get over your first love?
