I agree with everyone else that the marriage is over. Cheating and having sex with who-knows-how-many other men for 15 years. Wow. And he only came clean because he got caught!
Reverse the situation: How many husbands would stand by their wives if they found out that their woman was cheating on him with untold multiple partners over 15 years? Nobody.
Your husband's lies, deception, and infidelity has ruined your marriage. I'm so sorry that this happened to you.
