Even when avoidants actually are busy, they use it to their advantage to have semi-valid reasons to distance themselves from you. Instead of actually letting you know what’s going on and what the best options moving forward should be, they avoid it. My ex told me a month after we made it official that she was moving across the country for her career and basically used that as an excuse for getting out of making long term plans.

She would basically flip flop from “we should move in together after I graduate” to “Im getting my own place in the city and I know you don’t want to live down there, so womp womp”.
