Kiwi - Forgive me for asking but did W have an A ? I cannot understand why ( unless there was abuse ) why any woman would leave a marriage , unless there was someone else.
Even then unless OM is in picture, why would you continue to choose to be seperated.
If I was in your shoes I would definitly stay away from anyone else until you are 100% sure that you are over your W. Not fair on anyone especially your child.
