At a party yesterday

Saw the room where you and me

Had some fun

You thought it was love

Now I'm stuck here reminiscing

And I try day and night

Oh, to somehow draw a line

Wanna cross it all the time

I think I'm mentally cheating

How could I be so disobedient?

I'm just eighteen, don't have experience

Can't help the fact that I caught feelings, oh

I think I'm mentally cheating, oh

Cheating

Cheating, oh

I think I mentally cheating, oh

Cheating

Cheating

I think I shouldn't be looking in those eyes

Why do they give me butterflies?

Can't express how obsessed

Is it purely the attention?

I'm just trying to decide

If I stay, I'd have to lie

To myself, feels like hell

To be in love with someone else

And I try day and night

Oh, to somehow draw a line

Wanna cross it all the time

I think I'm mentally cheating

How could I be so disobedient? (Oh)

I'm just eighteen, don't have experience

Can't help the fact that I caught feelings, oh (Oh)

I think I'm mentally cheating, oh

Cheating

Cheating, oh

I think I mentally cheating, oh

Cheating

Cheating

So goodbye, I'm out of time

Only said I love you twice

I know that is not a crime

I need more to keep you mine

So goodbye, it's alright

Baby, it's a part of life

Something's gotta sacrifice

I think I'm mentally cheating (Oh)

How could I be so disobedient? (How could it be so good?)

I'm just eighteen, don't have experience (I'm all done, don't wanna feel this)

Can't help the fact that I caught feelings, oh

I think I'm mentally

Oh, cheating, oh

Cheating (Oh, it gets old)

Cheating, oh (Yeah, yeah, yeah)

Mentally cheating, oh

Cheating

Cheating

I think I'm mentally cheating
