how often do female avoidants come back?

I don’t want to gender this but majority of the post i see are guys coming back. Me and my ex were pretty secure and we broke off those toxic attachment styles after 2 years together but as we were forced to do ldr because of college she said the relationship was becoming too much + shes stressed with nursing school. It kinda sucks because no one rlly did anything besides her wanting to focus on herself but after that is there any possibility she’ll come back?
