I am looking for advice on how to tackle this.
My lovely DP is a clutterer and a hoarder. He has his elderly DPs living with him as their house became uninhabitable due to excessive hoarding 
We have nearly finished clearing their house to sell up and buy them a nice bungalow nearby but meanwhile all their stuff is crammed into the ground floor of DPs house.
His adult son is home and out of work and lounging on the sofa. 
The cupboards in Dps room are full of all his stuff and his DPs overflow. There isn't even room for me to keep a washbag and knickers in a drawer.
I have slowly cleaned through the house and cleared out the kitchen and bathroom and ruthlessly thrown away masses of stuff. but DP has inumerable electric gadgets and equipment and his hobby involves equipment that most people own one of. He has over 30 sets crammed into the garage and house!
Now I live up the road in a clean tidy comfortable clutter free home, but would like to spend more time with DP in future. Bear in mind his ExW left because she could bear it no more, and he REALLY wants things sorted so
the house is welcoming. Currently nobody visits - it really is CHAOS there! The whol efamily need to learn better habits.
Would you a. run for the hills b. give him an ultimatum and wait for him to sort it c. turn into a control freak and make him clear it or d. pour a glass of wine and chill out then go home and ignore it?
He is truly lovely but I couldn't live there even if I could jam my suitcase in somewhere...
