What changed? (jacob)

Everything was normal
back when we were just friends
we used to be so happy
i never thought that it could end

i thought i wanted nothing more
than to have you to call my own
but now that we're together
it seems everything goes wrong

we used to laugh for no real reason
now we argue about every little thing
i used to love that we were so close
now i hate the fights that closeness brings

we used to just hang out
and everything was fun
now i can sense that we're in trouble
like we're staring down a loaded gun

when I'm wrapped up in your arms
i feel like everything will be okay
but you don't hold me anymore
so i never feel that way

i wish i knew how to fix this
and go back to how we were
if we try than we can work it out
but I've never been less sure

the problems surround me like water
and i can feel that I'm starting to drown
I'll never know what changed between us
but the smiles turned to frowns

being around you felt so natural
but suddenly its hard
I'm so confused and scared
scared that you'll break my heart

i was afraid that this would happen
but you said it was the right thing to do
I'm not saying this is your fault
i just cant imagine losing you

i love being your girlfriend
but if i wasn't i think I'd survive
however if i somehow lost you as a friend
i wouldn't even want to be alive
