my ex (many years ago when i was a lot younger and willing to put up with a lot-my standards where not just on the floor,i buried them)
i walked into the bedroom and on the floor where a pair of jeans (pants inside them) and they where soaked (and i mean soaked-the pants where brown and it had hit the knees of his jeans) in dried shit-they had been there a while and oh god,the smell-you couldnt miss it
he must have had an accident and taken them off to go for a shower
why he didnt pick them up and sling them into the wash,i dont know as he only had to walk 2 extra steps to the kitchen/washing machine
nope,he left them there,sunny side up on the floor-we had to step over them to get into bed!
i got the ick so badly and left the next day-no surprise to learn he treated all women like shit too (the girlfriends after me-its a mystery to him how he can get them,he just cant hold onto them)
my own dp,not long after we'd moved in together,had an accident and cleaned himself up,cleaned the loo,brought his clothes down,put them in the wash and admitted what had just happened
i dealt with the temp and pressed 'start' (i do the washing which i'm happy to do-he pulls his weight with other things)
i've had accidents myself but did exactly the same as dp-you don't leave it for someone else to deal with
it happens,everyone has an accident,its how you deal with it that matters
