We just went into our apartment. The gf was changing baby's diapers in another room while I was in the kitchen putting the wheels back on the stroller.

She said she needed my help. It took me literally 5 seconds to finish the job so I put the wheels back on and went over to help with changing.

She immediately got pissed and said "our communication is shit and you never want to help me". I'm doing so much shit around the house so I wasn't having it.

I kept my calm and said: "I think the communication is fine and I was trying to finish doing my stuff"

Blablabalabalabla she's accusing me of some more bullshit and I just walk out of the room and she's pissed to hell.

I know I could have probably handled it better.

How do you guys deal with that stuff?
