I used to do this at work. It was based entirely on my confidence level. I compulsively apologized because I fucked up so much. It went away after I got better and more confident in my trade. Maybe try building up her confidence in areas you find her compulsively apologizing in. Does she do it more in certain situations? With certain people?
As someone who is in incredibly extroverted, you just have to take the hint and move on. Being ghosted is many people’s solution to the problem of “I don’t want to be around that person/do the thing but I don’t want to be impolite.” Just gotta accept it and move on to the next person you want to annoy into being your friend.
Yeah our opinions don’t really differ much save for some subtle nuances.
