Welcome, In recovery, aa programs really want the a to work only on themselves. They can't think of anyone but themselves. So this is normal. give her time. Let her take the time to get healthy and think of her sobriety. She needs to give 200 percent to make it last. No drama from the boyfriends. Be there if she needs you only.
Let her go, as she needs to fight this battle all by herself, you can't help.
Hugs my friend, what was for you, won't go by you!!
