It's normal that this situation should stress you out a lot. Just remember the silver lining on all this. It sounds like the law will soon take care of this woman. Your husband and his children are so lucky to have found someone like you, so understanding and loving... someone who cares so deeply.

You say you're best friends, but have you told him how you feel? What you're going through? The anxiety you feel?

Take time for yourself as well. Try and free up some time in your diary for some time to be by yourself or do something just for you.
