They probably weren't the right sort of girls if they were more interested in a drunk "sloppy" you. Finding someone to spend time with doesn't happen over night, hell, it can take a very long time. To be honest if you can't find ways to be happy with yourself it doesn't seem logical that finding one particular person is going to change that. What do you do when they need to go off on their own for any specific amount of time? Hang around and wait? There is no outside solution to this problem.
