No ...you are hurting yourself by wasting your time with a guy you can't trust.
No, you'd really be hurting her by leaving him because then he has no one left to cheat on but her.
Damn well said lol
No, she doesn't care- she only wants him for sex, she probably likes that you occupy him otherwise so she doesn't have to.
Unless she was once your friend, why do you care about her? Your husband is the one you should be thinking about. Start getting your ducks in a row, because unless he is truely sorry and wants to go to counseling,church, etc, you can't trust him ever again..Good luck
