Wow, it feels as though you wrote that about my marriage. You are definately not the only one who feels a bit stuck and unsettled. I still think love is a choice, I don't believe in soulmates. I also love my husband, but I feel that he doesnt' really get my needs and we just kind of exist next to one another... I wish I had some good old fashioned advice to help with this predicament... maybe you should try drinking a glass of water upside down? (I suddenly miss my grandma... she always had such random advice)
This is a really tough problem, I think it's especially hard because on the surface it does not seem that there is any need for concern.

Wishing you luck and wisdom is all I can offer at the moment.
