Martina, if it's any comfort, my marriage is in almost exactly the same spot. My husband and I haven't been intimate for more than 8 years (!). We were in couples counseling, and that was helpful while it lasted, but the last session ended disastrously. He has never said a word about it since, and it's been about 8 weeks. We never go out, either, and we're supposed (per the counselor's suggestion) to have a date night at least once every couple of weeks.
We used to do "cuddle time" each night, but even that has gone by the wayside; it's been several months. And my husband rarely, if ever, touches me, just a quick peck on the lips when he arrives home from work.
Like you, I long for some physical and emotional affection, just a little, even a word or two.
I am truly sorry to hear you sound so unhappy. Have you suggested couples therapy to him? It did help me and my husband for awhile; it provides a safe, more protected environment in which to communicate.
I wish you the best.

Please do keep us all posted.
P.S. And I'm sorry he laughed at your Love Dare suggestion.
