Jack....I agree that it is important to have a clean bill of health from your spouse after an affair....or possible one...but to ask before the relationship is back on solid ground is not a good idea because
the spouse feels that you are making assumptions that they are back for good...
the spouse will feel like you are looking at them as if they are disease ridden idiots....
Now I am not saying that we don't have a right to feel the way we do but if your objective is to win your spouse back I feel it is better to use protection until you KNOW you are BOTH on the same page of things....
As I said....I have been through this with my H....and when the time came he even let me go with him to the doctors and to the labs and to see the results....so when the time is right you can get what you need to feel comfortable again....before then you treat them as you would any "new" sexual partner!!!
