that depends.... on what you mean by "She dissociateds a lot, all the time"

heres why... its normal for people to dissociate.

dissociation is one of those things where even people with out mental disorders do it every day of their lives. what makes it abnormal is 2 things....

1 whether the person who is doing it feels its a problem for them
2 whether they meet the diagnostic criteria for having a mental disorder
3 which mental disorder they meet the diagnostics for... there are many dissociative and non dissociative mental and physical problems that have various forms of dissociation with them.

first you stated shes your ex. that in itself says theres nothing you can do to help her. think of it this way would you want your ex girlfriends, ex boyfriends coming to you trying to come back into your life where your mental and physical health problems are concerned after you have broke up with them.

many people who have been in relationships break up and are no longer a couple for a reason... they dont get along, one is more controlling then the other or they just dont fit together as a couple anymore, so they have decided to go their separate ways.

when boyfriends and girlfriends go their separate ways by breaking up they no longer have a right to things like what goes on in the others mental and physical health issues.

if your ex ...... asks.........you for your help then you can ask her how you can help her. then she will tell you what she needs from you, what you can do for her. until then theres nothing you can do to help her.

on the other hand what you can do for your self is contact a mental health treatment provider, they can help you to understand what the dissociative issues are and how you can help your self through knowing that your ex may have a dissociation problem.

Im sorry I cant be more helpful on this but since you and she are ex's now not a couple that knocks out any ways for you to help her unless she asks for it, then she will tell you what she needs.
