Could you completely walk away from people you have been friends with for over 7 years?

i have been friends with this group for over 7 years. But more and more i am finding that we have very little in common. And they tend to be a bit condescending. And have a whole lot of double standards that drive me crazy. i have been pulling away from them more and more. But i really don't know anyone else around here. i work from home and i am NOT into the bar scene. i feel so selfish. Because i don't hate them but i am coming to resent them. A part of me just wants to walk a way and the other part says no then you will be alone and hurt people that you had grown to care about deeply until this last year. Any thoughts?
