Sexting men and women is that cheating?

Husband met a woman in a bar when I walked away he started texting her a secret for 5 years. Said he never met up with her. In the meantime, he started sexting a friends girlfriend that was for 3 years. Then she gave her mother's number to him because the mom was having relationship issues with her boyfriend. He would text her everyday. I met the woman not knowing they were texting. We were at a motorcycle function and he introduced me. Later that day I said have you ever talked to her before and he said no. Here after searching phone records he was texting her 2 weeks before and that morning and everyday for a month and a half. Till I put the breaks on it. So he lilies to me everyday. He was also having sexting relationships with 5 men. Said he never met up with them either. He lied to me every day for over a month with that too. Kept making up stories because he was embarrassed. Should I stay with a man who had no regard for the love of his wife? I think how he didn't care. We have seeker council and he hasn't done anything as far as I know. But he broke my heart. During our marriage,I was faithful loving, caring good in bed. I can't stop feeling hurt. Do I stay?
