I don't think it's a bad thing to want to enjoy things in life with others....but I guess if the thought becomes over bearing....like you can't enjoy anything on your own (or you start not to enjoy life in general), then there may be deeper issues to explore.
Maybe look at situations when you do enjoy life....what is your relationship to the people around you, what's happening, how are you feeling, etc?
