Most Helpful Guy
I've had a friend break up with a guy because she thought he might cheat on her later. She THOUGHT he MIGHT cheat on her LATER. He didn't have any regular cheater signs like flirting or texting other girls. She just had a dream about him cheating and went with it.
There are also other stupid reasons I've heard of:
He was focusing more on school work more than me.
He was driving an old run down truck and it was ugly. (Remember, this is high school. Most people have sh*tty cars)
I wanted to show him how much he needs me and would miss me. <--- This takes 1st
