My addiction is slightly more understandable. All in all, we have 10 horses in the pasture right now that are rideable (though there's only ever 4 of us that ride, and that's at the very most). We've got about 30 halters, maybe more counting the nylons that we never use, only 4 saddles though (lost the other 6 in the fire), 8 saddle pads, ready-to-go bridle setups for 7 horses and several more bridles with no bits or reins. There are probably 15 additional bits with no bridles and I always try to keep 3 or 4 extra pair of reins around. We used to have a ton more before the fire but that pretty much wiped us out. What we have now is what's been bought in the last year or so.
Oh, and did I mention that we also have 3 sets of harness for a single pair of big horses? LOL.
