You will find a way to leave the door open a crack to your husband should you both decide that you want to work on the marriage. The thing about "tough love" is that it is an act of "love". Having enough love for yourself and your H to remove yourself from a disrespectful situation which, if continued, will erode all respect and love between you. This breathing space is essential. It is good to rediscover yourself and who you are outside of a M, especially a long one. Use the time wisely and if and when your H comes around, it will all stand you in good stead.
