I know what you are feeling as I too don’t have any friends. However the only time I really talk to guys is when they ask me to do a favor for them. Why not offer a guy who you trying to be friends with, help with something if he needs it? That is a start towards maintaining a friendship. Ask business1 for advice on how to do it he is more equipped to tell you what to do.
But I gotta tell you be careful on how often you agree to do a favor for them. Since I did it way too many times, and by the time I realized that they were just taking advantage of me, the friendship was already over for good.
