What should I do regarding my housemate?

I'm a 26 (M) my housemate is 28 (M), his GF is 21. We've been living together for approximately 4 months now. We technically are good mates but I'm not too sure currently...We've had our fair share of arguments and fights. We don't have any fences on our property and my housemate's dog has been found on all our neighbours' properties, one knocked on the door and asked us to contain our dog. Our neighbours fairly regularly find the dog on their property and drop it back round. It happened again today and I asked what are you going to do about the dog? (We rent and I don't want any complaints about it) he said “nothing, it's my dog it's none of your business”. I then proceeded to say well it is because it's my house as well. So here's the problem that consistently arises. I'm big about being able to talk and communicate about things being housemates, I make sure to go about things in a calm and non-whining or complaining manner. But when I bring anything up he will instantly spin the conversation about me, gets angry, becomes defensive then turns it into how he's been off me for weeks and I'm the bad guy. Every time without fail. I'm a non-conflict or violent kind of person so I generally wear it.

Anyway so today as soon as being confronted by my concerns he begins saying how he's been off me because I getbelligerently drunk once a week and saying he’s lost all respect for me. I will admit I’m not a great drunk, I am loud andsloppy. I probably have said some rude things to him when I'm drunk, I promise to work on it but I do spiral back and gettoo drunk... I'm not perfect. He knows I've had a drinking problem for 10 years, I was even a full blown alcoholic for a few years there. I've gotten a lot better but still have a long way to go in recovery. I am seeing a psychologist andcounselling to help with drinking and other life problems. Another example was when we first moved in together they were very messy. On numerous occasions they wouldn't clean up after themselves after breakfast/dinner etc and I politely ask to try clean up after themselves then every time I did that I got ragged at and taken shots at trying to make me feel likeshit. He blames this behaviour on his father. He never apologises or ever sees himself as being in the wrong even when he clearly is at times. He's never wrong.

Am I overreacting? Do I even say anything to him because I’ve had this conversation with him before. Do we just ignore eachother?
