Need some unbiased advice 

Any advice? I have been married for over 17 yrs.  2 1/2 years ago, I discovered my hubby was having an emotional affair.  He claims they were just friends and that he no longer talks to her.  We have recently moved and we are "having a fresh start"! I caught him over the past 2 1/2 yrs lying to me about little things.  I have given him a final chance.  I do not beleive there has every been anything physical, mostly just him seeking female friendships.  Well, our "fresh start" has encountered a hickup.  I am unemployed and job websites suggest running credit history to see what a potential employer might see.  Well, I did and found under his credit history there are 2 credit cards I do not know anything about.  He claims one is his new job, and he is checking on what the other is. In the meantime, I found one the credit cards in his wallet.  There is only a small limit, which is odd, our cards we have usually are platitum or higher.  There is a $700 limit and he has a $400 balance. I found a receipt today for a money oder he purchased to pay for this account.  There have not been any bills coming to the house, he lived in our new state about 6 mo prior to the family coming out and he used that address.  He just recently opened this account.  Not sure where he is going to have the bills sent to now that he no longer will have an alternate address.  He keeps telling me how happy he is that we have worked things out and are moving ahead as a family.  I know this is stupid, but what is that or those (2) cards used for?  He is not staying late at work, is not really on the computer when I am not around (it is in our kitchen), is with the family on weekends travels occasionaly for work, but no regularity.  Ihve been checking his personal cell and nothing jumps out, he does have a work phone, but that is monitored by his employer, so when is he having time to do anything and if he is doing something,what is it?  Our sex life is lagging, usually 1-2 times a month, but that has been about our norm, at least after job, kids, life..  What should I do with confronting him on the cc?  Any ideas on what he is "doing"  I don't get why he is telling me we are getting a fresh start, and he is so happy, yet this is hanging in our lives right now??  HELP?????
