19th anniversary

Today is my 19th wedding anniversary. an I have spent it alone.my husband worked when he could have took the day off.and when he came with a card.He kiss me bye an went to a friends house. I just feel hurt .like 19 years of faithful , honest marriage doesn't matter.don't get me wrong .there has been ups an downs lately we have been going through a rutt in our sexlife .I want it an he doesn't..an there has been arguments over it see I am 50 an he is 44.when I married younger it was for love but it was also someone that I would have to keep up with me in every way.I don't know should I be worried? Are my expectations to high? It gas never been like this before.
