Am I overanalyzing? Ex wants to be friends? I'm confused?

you can become friends with her, that is already a first step (better then living as enemies)
Don't mind that you told her that you did not wanted to speak with her, people tell so many things in break up.
Women are in doubt after breakup, if the did the right thing or not.
You should leave her alone, if she calls you tell her that you are short in time that you will call back later. Call her back but make it short as well, give her the feeling that she is not your priority!
This will trigger her mind.
In the meantime do cool things with friends or alone, get in shape, buy some new clothes, horsebackriding, movies, travel, surf, etc.... (don't tell her about it, she will find out for sure)
don't post stuff on facebook about lovesongs, lovequotes, etc... post cool things you do with friends

If you want her back this, is the way. Use your brain, not your heart at this moment AND be patient!
