I would say to the person "Look at me Sue, you have a problem here. Would you like to talk about it" What happens next would depend on her. If she accepts that she has a problem, there may be a possibility for our future (I'm really good at clearing, cleaning and organising the house and great at DIY) I also accept that she may continue to be untidy and that I would have to treat that as normal. Of course, she would have other positive qualities which I found attractive, in the first place. I know three people who are hoarders and have their home in a messy cluttered state. Two of these do not want anyone to interfere with their "things". The other one would be happy if someone took charge of the home.
@HippieChick58 You said you wouldn't say anything to any body!
LOL!!
How the hell did you get a picture of my kitchen?
I have cleaned a lot of places that looked even worse then this place, if the whole house is like this they are pretty much on their own, for they have been for FAR too long now, prolly no saving them...but if this mess is religated to just the kitchen then they have been alone for far too long and just need some encouragement and help, I woulod bring in MY OWN cleaning products and a resperator just in case of mold, afrais to look what is hidden under the towel over the stove... but this def isn't a game ender by any stretch, if the dates are going well then there is hope, on saving them from themselves. I never say never unless it is absolutely unavoidable.
The person whose place it is got mental health issues for sure. I wouldn't be able to cope with it. Funny enough I experienced something similar once, not so extreme though. Run away .....
Probably safest emotionally in reality
The first thing I noticed is the pack of cleaning sponges top centre, between the milk and metal bowl, which suggests the person who lives in the house intends to do something about it. I'd try very hard to get them the support they need to be able to do so.
Assuming good physical hygiene was being practiced, I'd just be honest and likely invite to my place. If he didn't understand what my concerns were then there would be a problem.
