What do i do?

I go out with him but love you
will anyone please tell me what to do.
I don't want either one to be hurt
But when I'm with him i feel like dirt
you on the other hand are kind and sweet and have never broke my heart.
and he plays with mine like he's playin darts.
sometimes he'll hit , sometimes he'll miss.
and when im around you he gets pissed
but i guess its whatever your with her
just remember i love you and id give you the world
