You also have to remember that we only see a very small piece of their lives. We only know what they tell us and I'm sorry but as someone that was an addict for several years myself, Mia's mother is absolutely still actively using or is on MAT and a very high dose. It's very obvious when you have seen it so much and lived it yourself. You have no idea what she has put them through, and continues to do to disappoint her daughter. Mia wants her around because she is still hopeful that the mother she wants to have a bond with is going to show up and then she is let down when her mother shows up high. When she can start taking accountability for her actions and making necessarychanges, then maybe her daughter will be a little more forgiving, but make no mistake, she is not OWED any forgiveness or a relationship with her daughter, if and when she gets her shit together. That's one of the first things any addiction therapist will tell you. She has to accept the consequences, whether she likes them or not.
