Always a cheater. There's nothing more than I hate than that phrase! Yes cheating is bad but a lot of people change. I'm not saying forgive someone for cheating on you, I'm saying don't decide to not date someone because of a mistake. My fiancé was stupid when he was younger and cheated on everyone he was with a lot. However, we've been together for six years and I've never even had a doubt about his faithfulness.
