Update: guy i live with is draining me

I posted about a guy who was subtly rude to me all the time that I live with.

Something happened today which is really confusing me. I was chilling out at home on a bean bag in our kitchen and I was in a GREAT mood I had just had a really fun flirty moment with a girl and we exchanged details (through the window it was very cute) and I was in really high spirits.

Then he came home and I was chatting away to him feeling pretty good then he threw out a totally out of nowhere "joke" he basically said "maybe i should try your tea as everyone in conversation is repulsed by you " (obviously doesnt make much sense without context but trust me it made sense) he apologized right away because I think he realised it was a bit rude but I stupidly said "nah dont worry it was funny" and later on our other roommate came into the room and he made a "joke" saying how "we provide the cleaning utensils while he provides the need to use them" talking about me. Now I had literally cleaned the entire kitchen an hour before this so it's not really a fair accusation but he claims that I leave dishes behind even though after the first time he said that I started to make sure to leave no trace behind me but he still talks as if I do.

Anyway my mood totally dropped and I'm really sad that I let him get to me but also sad that I no longer get to enjoy that awesome wave that cute moment with that girl outside the window gave me. I literally just feel bad and depressed again and I dont know how to deal with the situation I've dealt with this kind of behaviour before and its always a sticking point for me, I can handle overt aggression that's fine its just this low grade constant subtle aggressive behaviour I just dont know how to deal with and its making me miserable please help because I can't truly relax until I know what my next step is because it's really making me feel low
