Some people do set themselves up to only get "deeply involved" with those who they know they have no real future. It's another avoidance issue, I think. Those that she can "have it all" with then, she won't have.

I have a good friend who is the same way. She's a successful business woman dealing with issues but does well. She will NOT keep a relationship going that can go somewhere solid then will stay in, and chase, relationships that are doomed (men in relationships already for example).

We talked about this and she recognizes this in herself. Since then, she's told others similar to what your friend has because she does very well know it's "her loss" potentially.

I wish you well.
