I have been in an emotionally exhausting SSM for over 5 years. Please believe me - you have to do something about it. I just "gave it time" and everything just got worse and worse.
Here is my advice, for what it's worth.
1. Find a marriage counselor that does sex therapy. Contact them and set up an appointment, right away. 2. Go to that appointment and bring your husband. If he won't go, make sure to go and see that therapist anyway. Eventually you will be able to figure out how to get him to come with you.
You still have time to turn this around. I probably don't, and I can tell you first hand that you are probably looking at a very serious, marriage-threatening situation if this is not addressed quickly and effectively. Be proactive. Be provocative and get in his face. Value yourself, and insist that he meets your needs. You are worth it and you deserve it!!
