Ok I'm 100% sure my SO wet the bed & didn't tell me. I had slept on the couch one night when I was sick well next day sheets were changed which I thought was weird but didn't ask why.. today I'm doing laundry and the sheets and clothes smell of piss- (his stuff. )Should I ask him or let it go? I'm not mad or anything & this hasn't happened before so I'm sure he's embarrassed should I just let it go?
