Overwhelming mess!!!!

Kitten

Ok so I’ve been with this guy for five years. We’re finally saving up to move in together, but the house he lives in is a fucking MESS!!!! Bugs, trash, and DISHES OH THE FUCKING DISHES. I spent over $100 this last week on cleaning stuff and he shows no interest in helping me. I am so overwhelmed by the magnitude of the mess he and his lazy ass mother have created and I’m losing my mind over here!!! Help?? Advice anyone??
