It sounds like she has trust issues. It does not matter if you were separated when you had a one night stand or that she is looking for dates. She needs to trust you in order to be intimate with you. Women and men are so different when it comes to companionship. Reread DB and get to work. You can still save your marriage if you look at yourself with a clearer mind.
