J.S.
I really like what most everyone else had to say. I know I've felt taken advantage of or attention deprived at one point or another in my 12 year marriage. My husband is not the romantic type at all, and I accept him the way he is. If I want romance, I know I have to provide it or ask for it. Husband is pretty good once I've asked for it.
If you feel like you're being ignored, then you are. I don't like that your husband disregards your feelings. You feel what you feel. Can you talk about a solution together? What would make you happy? If you need some one on one time - then arrange it.
Before you talk to your husband about this (and I think you should), have some solutions handy. Know what would make you happy - even if you have to make the arrangements yourself.
And about being demonstrative and affectionate - are you that way to your husband? Do you touch him often? If you go and hug your husband, does he hug you back? Or if you try to kiss him, does he turn away? If he spurns your affection (for lack of a better phrase), then I think something deeper is going on. Marital counseling may be in order here.
I hope things work out! Let us know how it goes.
