Did you face the person your partner cheated on you with?
I was with this guy when I was in high school. He went to a different high school, but my neighbour (next door to my parent's house) came over and told me she saw him up town with another girl, holding hands. I didn't believe her and thought it was bullshit. My mother had to pull me away from my neighbour, because I wanted to punch her for being a bitch. It turns out he did in fact cheat on me. I was only 16 and I was so upset (being the first true boyfriend). I didn't actually face the girl he cheated with, but she wasn't anything special (apparently).
