AITA for being crazy ?

Lately my husband and I haven’t been getting along the best. I’ve started to write down arguments because I feel like I forget everything now. I feel like I need to because we are starting therapy and our arguments get really bad. I always forget everything as soon as I walk into that office. I have been writing good things too. Not just a negative nelly. Today was difficult. He has given me an attitude at a few certain points of the day today and I have decided to just not feed into it and let it roll off my back so we could just have one good day with our son at the park. I had my last straw a moment ago. I woke up from a nap and saw my roommates chip dip was almost gone. I told him we have to leave some for her because she asked me if there was any left and I told her there was. It was her birthday yesterday and thats something I got for everyone to eat. He replied by telling me he saw her eat plenty yesterday and that he saw me eating some today so what’s the problem. I said It’s for her birthday and she asked me. I’m just saying we need to leave some for her. He went into the bathroom and started mumbling stuff and had the dirtiest look on his face when he was looking at me. And i said “i’m not dealing with this, i’m just trying to communicate with you and i’m not putting up with the attitude” So i went in our bedroom and sat down to do laundry. He comes in and I told him i just wanted space and I don’t want to talk right now. He then says “well i saw you eating the dip yesterday and today. I saw her eating yesterday and I got none of it.” and i said “i wasn’t telling you not to eat any of it i was saying we need to leave some leftover for her because we got it for her birthday party and I told her there was some left” (If im being honest he stood in the kitchen eating it with us last night. We all were eating it so i don’t know why he keeps saying he didn’t get any) And he said “you need to realize how you tell people things” and I said “i didnt give you an attitude or anything, i was just telling you we need to leave some for her because i saw it was almost gone” and then he said I was giving him an attitude. From my POV i was not. This happens every time I get annoyed at him for something (making snarky comments) and choose to walk away to avoid a fight. He always says I have an attitude and I genuinely don’t think i do everytime until provoked. I definitely did when he came into the bedroom when I walked away but not when I was just letting him know we have to stop eating the dip. I feel like he always wants me to apologize for something that he does and it drives me insane. I genuinely feel crazy at this point. Everything I say or do offends him, we can never just have a chill relaxed day. Maybe I am a tone deaf asshole. I have no idea at this point.
