I'm going to go against the grain a bit and say that you should try to go out with other women. You may be a "safe place" for your friend, but if you keep being there whenever she calls, she will always be your friend.
Plus it's not fair to the guy she's seeing. If she's opening up to you, she's not doing it to the guy she's seeing which, in turn, isn't fair to his little girl if she's just playing games with him.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
