Input: Sorry this is a long one!  Basically I have lived with my flatmate for three years but with others. We were really great friends and then he went away for a year. When he came back we decided to live together just us two. He wasn't around so I sorted all of the viewings for flats etc. I was really proud of the flat (really cheap and nice looking, equal bedroom sizes which is difficult for a 2 bed). I lived there on my own for about a month and then he arrived. Ever since he arrived he has just basically treated the flat like dirt.

He leaves his leftovers and peelings everywhere, dirties all of (my) pans, chopping board and knives (we share) and then leaves them until he wants to use them next. Just lazy things like leaving food on the dish sponge and leaving the bin lid open with stuff poking out?? if I want to cook or eat I have to tidy the kitchen and wash everything up before I can make anything myself. This takes half an HR in itself! I have said about maybe just tidying communal areas and he said yes sorry he was just really stressed.. we are both at uni so I thought that wasn't an excuse but we left it and it was tidy for a bit but not long. I'm no neat freak but its things that make the flat smell and become unpleasant.
I'm super aware that it's annoying to have someone niggling at u to tidy up all the time but I genuinely feel like a cleaner and it is actually exhausting thinking about how messy it will be when I get back from work/classes. I have began to hate being in the flat and I don't enjoy spending time with him anymore. I feel like I'm just tidying up after  him ALL the time. I think we have just drifted. But I feel so bad constantly getting annoyed by it and feel passive aggressive when I tidy up. 

AITA for being so negative about my friend and essentially wanting to distance myself or is there something I can do to better the situation??
