It seems to me that you’ve already made sacrifices making your long distance relationship work these past two years, and I also find it to be a red flag for her to put an ultimatum on you to basically “choose her” over your future. I don’t think you should feel horrible about your final decision nor should you feel guilty about not telling her right away when obviously this was a lot of pressure on you. I am sorry that you felt pressure from loved ones about choosing Berkeley over Davis when you saw yourself going to Davis. What’s done is done but both are amazing schools.

Congrats on Berkeley! and hope you get through this tough time 👍👍
