It is true. The friend, who is now your most recent ex, was pretty low expectation. But --- ultimately you want more than that in a relationship. You want to be able to give and get more, it seems. Yet, it doesn't seem like you are ready for that quite yet. That's okay.

The ex's call?? Who knows? Probably the friend told her that she had a hunch that she was going to get dumped. Maybe the ex wanted to intervene. She probably hopes that you are over her and hopes that you don't have lingering feelings that are interfering with the possibiity of a new relationship.
