Have you two gone to counselling? Also, there are some great books on recovering from affairs, have you read any? I just think after reading your sitch and the pain in it, that you are going to need some help.
My other question is whether you think your wife has been totally honest. From what I have seen in the affairs I have witnessed, often the spouse that has the affair but returns remorseful to the marriage, then goes overboard the other way trying to move past it (lots of ml, lots of affection, trying to be an overly good wife/husband) and thinks that will make up for the past. Your wife is not doing this and it makes me wonder.
Hang in there, you will hear from some people on here with great perspective on this issue (paging Cinco...) CB
