Its ok, just keep prodding her on to find a therapist at occasional intervals. Somehow, I find that I'm a BIG TIME procrastinator when in the middle of a very depressive period. It might be what's happening with her.

A good therapist will not prod her to any realizations or make her make any decisions regarding the relationship while she is not ready. Instead, its simply a safe place for her to vent until she decides for herself what to do about it. A good therapist knows that you can't force anyone regarding decisions about relationships. If your friend is procrastinating because of that, let her know that a therapist won't force any conclusions on her and keep encouraging her to seek help. =)
