Mentally Cheating

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
