I have a real life experience for you, i was about a couple of weeks or so in AA and i had been hanging round with this guy he was absolutely insistent that i meet him for coffees everyday which i did, i didnt particularly want to most days but felt obligated to help him...
He would text me at all times so i had to switch my mobile off at night!
Anyways i hadf gotten a sponsor and started to work the steps so that became my main focus and understanding the severity of my situation decided to tell him that i needed to have some more time to myself to work the steps but if he wanted to start working them too and get his own sponsor maybe we could get together and discuss the Big Book each time we meet...you watch them run for cover lol
Remember like always attracts like, start doing something different and changing yourself and these kind of people wont want to even sit next to you...although you might be pleasantly surprised that a few months down the line when they see the change in you they might be asking you for help in a very different way:-)
