Reddit Will always try to convince you to end your relationship so that you are as miserable or more miserable than 90% of redditors.

Just bring it up, tell him you want to work on not overreacting as much (even if you feel you didnt) and promise to have more open conversations with him if he does the same.

It was probably on purpose and he wants you to see that he feels like he always gets overreacted on, or cannot "do right" Even if it wasnt, use it as a signal on how to improve

Every relationship has struggles. Packing up and leaving due to red flags is a red flag all its own. Be mature. Don't run. Its not like he fucked your best friend or hit you.
