I can definitely relate. I walked around a couple stores by myself tonight and now I'm watching TV by myself. I don't mind it, but it can be lonely sometimes. I surely could have found some bar/ club/ party to go to with friends but not interested in that anymore.
I like the idea of spending one on one time with friends. If they are a true friend, they will understand and will make time for you doing something sober. I will have lunch or maybe dinner with friends, but I'm not going to sit in a bar or party/ BBQ where the focus is drinking. What's the point? I can't talk to my friends once they are drunk. They don't listen or pay attention, lol.
