So we were walking along with my gf and another 2 friends of ours. Lets call one of them Jeny for now. Jeny was telling a story (a pretty interesting one at that) and my gf made a pretty relatable comment. We laughed and i hugged her. Here comes the problem....

I accidentally called her Jeny, (note: this was while we were still walking with Jeny and her friend, and i was still kinda mid conversation with her). We all laughed at it but later in the evening my gf showed her true colors. She was in a half-angry half-depressed state. And she kicked me out not 30 mins after she insisted i came over (top tier strat, ik). Now she wont talk to me and shes even thinking of breaking up.

Should i tell her shes acting like a moron over something so little? Or just realise that if something like this is enough to make her think of breaking up, things might not be going so well even if it blows over?
