Wedding & Weekend

Came back from my nephew's wedding tonight.  It was 2 hours away, so I stayed at a hotel in the city.  The wedding was so sweet, and they are so much in love.  It was held in a small church on a site that has an Acadian village around it.  The reception was in somewhat of a barn type building.  Live band, buffet, family; should have been a happy time.  I wasn't miserable, but I felt so alone, in a room full of people.  I was back at my room by 10, read a book, and went to sleep.  I did have a nice brunch, with my sister and her husband. 
I need to change my life.  I was there at the wedding, watching the couples, and you can tell who is truely happy and those who just put up with one another.  If my husband would have been alive, the evening wouldn't have been too much different.  He didn't like to dance too much, and was not too socilable.  I myself, became more like him over the years, and it became clear at the wedding.  Both my sisters are very social, have loads of friends, and are both married.  I only had my husband.  Now, I have to make myself do things, for myself. I asked one of my sisters if she wants to take dance lessons with me.  Even if she doesn't, I still will go.  I know it will be scary, but if this is what I have to look forward to, the rest of my life,  this loneliness, I will lose my mind.
I'm trying to be more and more friendly with people.  My husband was always so insecure, and wanted me to himself, I think I shyed away from being friendly to people.
It's a process, I know, but I have nothing but time anyway.
