Something interesting crossed my mind this morning... You may think it's depressing, but i really wonder how would you react to this scenario:
What if everything in your relationship was going great. Your spouse would carry you out on dates, introduce you to friends, made an oath to never leave you, and even went as far as proposing to you.
While everything was going 'good', you realise that there was something was wrong. Your spouse's kisses does not feel the same way, the communication between you both was depleting, and there is a 'gut feeling' that something's wrong.
