I was just with you on your birthday

And I met your whole family

But on the way homeYou kept looking at your phone

Couldn′t help but ask, "Who's that babe?"

And the way you said "Nobody"

I knew the rumors

They were more than just rumors

Maybe I should have noticed

You were just half in love

Maybe I should have noticed

That I′m not the only one

Somebody told me that you

Got another lover you've been giving it to

Can't believe I believed you

You were my-y-y-y-y girl

Somebody saw you with him

Now you′re try′na tell me that he's only a friend

Can′t believe I believed that

You were my-y-y-y-y girl

Ooh, ooh, ooh, ooh, ooh, ooh

Ooh, ooh, ooh, ooh, ooh

Ooh, ooh, ooh, ooh, ooh, ooh

Ooh, ooh, ooh ooh, ooh, ooh

Lately, you've been making excuses

And the stories ain′t adding up

But I just go blind, when you look into my eyes

Everytime that I try to confront you

There's always somewhere

You′ve gotta run to (Gotta run to)

The warning signs

They were more than just warning signs

(Woah, oh, oh)

Maybe I should have noticed

You were just half in love (You were half in love)

Maybe I should have noticed

That I'm not the only one

('Cause) Somebody told me that you

Got another lover you′ve been giving it to

Can′t believe I believed you

You were my-y-y-y-y girl

Somebody saw you with him

Now you're tryna tell me that he′s only a friend

Can't believe I believed that

You were my-y-y-y-y girl

Ooh, ooh, ooh, ooh, ooh, ooh

Ooh, ooh, ooh, ooh, ooh

Ooh, ooh, ooh, ooh, ooh, ooh

Ooh, ooh, ooh ooh, ooh, ooh

You were my-y-y-y-y girl

Maybe I should have noticed

You were just half in love (You were half in love)
