I dont understand

I dont understand
you spent last year
doing whatever you could to get me
trying to get a chance
when i was single
your girlfriend getting pissed
all those endless fights
you fought with your girlfriend
and me with my boyfriend
about the same thing
you need to leave him/her alone
its not fair to me i love you
and your with my not him/her
what i honestly dont get
is you finally got me
and it was everything
we ever wanted
or was it fake
because you dumped me like
i was a rock and had no feelings
but its funny how you loved me
soo much last year and you would
do anything to get me
and this year after we were done
i would do anything to get you
because i love you
