I folded
You said you wouldn't do something and then you got scared and did it anyway like a coward.
I told myself I wouldn't text her, but I did. And I felt like a total loser.
I said I wouldn't join the group chat, but I did. And now I'm stuck in a group chat with my ex.
I said I wouldn't eat the whole pizza, but I did. And now I'm bloated and regretful.
