Betwixt, Amy is right in that you should have counseling, and also see an attorney armed with your financials so you can see what your life looks like if you divorced.  Is your husband showing true remorse at getting caught again? Is he handing over his phone so you can see the activity on it? Could be he has a burner phone, anyway. It's a tough decision to make, be sure to have your ducks lined up. Word of caution: My girlfriend discovered her husband's cheating after 40 years of marriage. Other woman was an alcoholic neighbor. My friend left her husband and her adult children were angry at HER and wouldn't let her see her grandkids. Blamed HER for not putting up with his disgraceful behavior. (My friend reckonciled, but recently unexpectedly died, he immediately took up with someone else, and the daughters are NOW treating her memory like it was gold, where before they wouldn't speak to her. Sometimes I hate people.)So just be forewarned. Go to chumplady.com for support.
