AITA For telling my SO that I (33m) could not continue a very emotional/stressful conversation in a calm manner? Full disclosure: The stressful situation is my fault. 100%. 

I (33M) am learning how to deal with and express my emotions in a healthy way. Tonight, after we talked for a couple hours, mostly good, I knew I’d reached my limit. SO is hurt, upset, and crying. This makes me feel like a giant POS. BUT, I know if we keep the conversation going, I will say things that I don’t mean to come across in a mean way, but totally will because I get up early, get tired/lose filter early. 

I told her we would continue tomorrow.
AITA?
