So me (M21) and my girlfriend (F20) were in the car when we started talking about random business start up ideas and i mentioned 2 one of which was to sell human breast milk in stores and woman would be able to volunteer and get paid a good amount to donate their milk (ik its a stupid idea) but then she said only creeps would take advantage of that and buy that and i said well creeps would buy it but creeps can buy anything and i wouldnt be selling it for them it would be for people who walk barefoot to be closer to earth and that group of people. But then she started crying said she never heard me talk like that before and it was creepy and i apologized and said i shouldnt have said anything and that i didnt mean it in any creepy way i just meant it as selling any regular milk in the store but she kept crying and i kept trying to talk to her about it but she completely shut me off and I took her home. I know shes not the asshole but im just confused on whether i did anything wrong or not?
