18. Weird Confusion
I found out my ex-boyfriend (dated from 15-18) had been cheating on me when, upon walking into the apartment he shared with his mother and two elementary-aged sisters, the youngest sister asked me something that made everything clear.
Her: When did you leave?
Me: When was I here?
Her: You were here all night. I could hear you talking to [ex’s name].
I had not been there for two days at that point. I asked him what she was talking about, and he blew bubbles for a few minutes before confessing.
Good riddance.
