What a terrible position to find yourself in. Whichever choice you make tomorrow will have huge impact on your life, relationships, mental and emotional state. I know that you and your husband won't take it lightly but please take the time to listen to each other as well as talk it through completely as there is nothing worse than, "I wish I had told you that......" at a later date.
I wish you all the best for whichever path you walk down and please remember that you're not walking it alone, you have your husband at your side.
