I'd have become so disinterested if Arsenal were my proper team. Believe me I've gone through similar With milan after we fell from the very very top table, but there is now a project in place and whilst it's taking a long time, at least we are headed in the right direction and I'll be patient with it, even if my fandom for the club is slightly diluted since having been born into and taken constant success for granted.
The same is true of Arsenal fans in all honesty most of you are born into the club being one of the best in the world, but since 2006 just haven't capitalised, but you don't even seem to have a project to look forward to as it's just a complacent organisation altogether.
At least with milan the owners know they fucked up and didn't plan for the future and are doing something about it, trying to find passionate wealthy new ownership. They pissed me off selling Ibra and Thiago but we had no choice, at least they really do deep down want the very best for the club even if they have been inept for a long time.
I'd sooner ineptitude with a motion to change than just apathy that your team just gets crippled by.
