Let's be honest,you do not actually need to know that others think of the "emails" after all we do not know you or your husband, but YOU DO, you know how your husband talks, behaves and what is normal or not for him. I know all too well from experience the devistation affairs have and what a horrible thing it is to go through finding out or thinking your husband is messing around. Your gut instincts are a good indication. Has your husband lied about realtionships with women in the past, do you have access to his email account and password, what about cell phone and phone records, is he secretive, does he make excuses to leave the house, the list goes on and on, but like I said you know your husband better than any of us out here, if you think there's something going on you did the right thing by confronting him,now keep your eyes and ears open,do not be nieve and sit idly by and be taken advantage of, if there are children involved you need to begin to get your affairs in order as to finances, home equity amount, any retirement that is available, bank accounts, ect., that is if you would leave him if he is in fact having an affair. If you want to save your marriage I hope he tells you the truth whatever that may be and you can get counseling. If his email contact with female co workers bothers you and causes you concern if there is nothing to it then he should be willing to cease all contact even if he deems it as "innocent". Good luck to you and your family. I know nothing is more heart wrenching than loving a man and realizing he is not on the same page,that he is carrying on with someone else. I pray for your healing and devine wisdom as to how you should proceed with the information you have obtained.
