Am I in Love?

I gave him my gift(Sex)
but it only took a moment
he didnt say anything about my midrift
there wasn't much movement

Could this be love
or a pain in my heart
I think about him when I'm in the tub
we once went to wal-mart

I think to myself was it worth it in the end
what is he about
did i mention he has a girlfriend
when we're together I just want to shout

Why do I put myself through this
am I really his?
