how can the doorman take orders from your gfs mom? is the mom the landlord like she owns the apt and your gf just lives there or is the mom the one on the lease and she pays your gfs rent? either way if that happened to me the first thing i'd do is call 911 and have the cops come over have a word with the doorman....i'd guarantee he'd let you come in to get your stuff, unless your gf isnt home or something like that. as far as being able to stay there, i highly doubt any of this established residence shit will stick....specially if you've been basically mooching off the gf by staying there and not paying rent....they can kick you out anytime they want, there's no obligation to let you stay there if your name isnt on the lease and you're not paying rent.
