Amanda, I was just wondering how long you and your husband have been married for? Does you husband have a stressful job that could be putting pressure on him? Do you think perhaps he has found someone else?
Is a difficult situation to deal with.
If it's just the sex being affected, maybe some quality time spent together to just relax and talk could open things up a bit? If he isn't being as sensitive, maybe he just can't be emotionally right now?
I do hope things work out for you.
