I found something disturbing in my 19-year-old’s room. Looking for advice on how to handle it.

Hi everyone. I initially posted in r/relationships but the mods suggested I come here instead.I’m kind of in desperate need of advice on this. I usually go to my parents with questions about marriage and family and whatever but I’m too embarrassed so I thought I would finally make an account and try here.So the other day, I was cleaning up my son’s room. I wasn’t even snooping. I was trying to do him a favor. He just got laid off from his job (it wasn’t his fault as the company went bankrupt). But he hasn’t been looking that hard for a job since. My husband and I sent him off for a week to visit his grandparents. He’s holed up in his room all day and only comes out for food so we thought this might help.What I found were eight gatorade bottles filled with what turned out to be urine. At first I thought it was the actual drink but the color was off and they had clearly been opened. So I took off the cap and the smell hit me. I almost got sick.I’ve gotten rid of the bottles and told my husband what happened. He agrees that it’s odd but doesn’t think it’s a huge deal since “men pee in weird places sometimes”. I told him it’s absolutely not normal when he could go to the bathroom right down the hall. It’s not like we live in the wilderness. I told my husband I think he needs to talk to someone but he disagrees. He says all our son needs is a job.I don’t know what to do. Am I overreacting? Should I call him while he’s with his grandparents? Talk when he comes home? And then what do I even say?I also don’t know how to convince my husband that there really is something wrong with this. I’m convinced my son is peeing in the bottles because he just doesn’t want to risk seeing us. He avoids us like the plague even though we’ve done nothing to him. He’s technically an adult so I try to give him some leeway but he is still living in our house, after all. I have brothers and I don’t remember them ever acting this way.I’m honestly concerned but my husband is treating me like I’m worked up over nothing.tl;dr - found out my adult son has been urinating in bottles; not sure how to handle it and my husband thinks I’m overreacting via /r/Parenting http://ift.tt/2hZB7Ug
