Afraid and Fearful

There is a book out there called "when good people have affairs" it might help you pin point the reason you allowed yourself to cross the line.
Living in limbo is a tough place to be, only time is going to show you which direction your life will be taking.
Continue to be supportive of your spouses feelings, give him room to work through things, also be careful to project what you think he should feel. After all only he truly understands that. I wish you peace, be strong, you will make it through this to the other side! (((Hugs)))
