Truth is always truth dude. You met her and might get married. Tell her everything and don't wory that you will loose her. Marry the women who is okay with it.....Past is past dude...Be careful in the present and future that's all. If u have any kids that is the different thing rest should be fine. HOw can u be sure that lady did not have any relationship with anyone. It is just a luck dude. Who cares anyway....
