Once a cheater always a cheater?

Am I the only one who considers sexting another girl, as cheating?

I warned him once before id be gone if he did it again, and he did it again in a 6 month span. I broke up with him, but he keeps trying to get me back. He swears he will change. Do they ever change? Its hard because I just want to hold onto the good parts of our relationship, but im so hurt I feel like i wont be able to trust him.
