I used to read them until the end of the Governer storyline where EVERYONE DIES except two.
I kept reading to the point the two survivors reach some bizarre delusional upper middle class gated community where everyone pretends there are no zombies or something. Also Rick was talking on the phone…hmm.
At this point I quit knowing eventually something will happen in the community and it will be overrun etc etc ad nauseum repeat etc.
I picked up a more recent comic and noticed Michonne is back somehow, is it worth reading the interval I missed and new ones? I think what put me off was the comic seemed to be going nowhere, or Rick was slowly being driven insane by loss. In fact I started guessing the last issue would be Rick finanlly stripped of everything that gave his life meaning accepting death and moving on(the zombie world being metaphorical etc).
