It started out with a kiss, how did it end up like this?

I was doing just fine until the kiss then I was falling asleep and she was calling a cab. He was having a smoke and I saw her take a drag and they went to bed and my stomach feels sick and I'm just telling myself it's all in my head but I saw her touch his chest and he took off her dress, I just want to be let go. And I just can't look because it's killing me and taking control. I have jealous and it feels like I'm swimming through sick lullabies and I can tell she's choking on her alibis but I guess that's just the price I pay and I feel like destiny is calling me to open up my eager eyes, how do I look on the bright side?
