Is it normal that i want to move away but somehow find myself back there?

Okay me and my mom will have arguments about lots of stuff, mostly money and who does what with it. I sure buy pot and bowls and normal pothead stuff, but I leave money on the side for help with groceries bills etc., but everyone used that money for their shit and said I needed to actually do shit with it or buy stuff that isn't what I focus on.

I finally told them all to fuck it, and moved out and I'm wondering I did a right thing. I know mentally I did, because of the arguments got so bad cops were called regular and finally left.

Then they call me crying for me to go back and that they were saying the house was is falling apart without me. Then I get there and a week goes by and finally it all goes back to normal arguments.

It's gone as far as they tell other people I'm a methhead and a thief, but when it comes down to it they cry for me back and fill me with hopes of promices and things will be different. Am i crazy, but is this thing normal in families? Its happened since I turned 16 and im 18 now.
