It's been several in the range you mentioned. Time and after time, you get sick of the whole "oh don't worry there's someone that'll treat you right out there" speech. I think everyone should take a good amount of time after they get out of relationship to find themselves. I learned alot from the perspective of not being dependent on someone and realizing what I really want in my life.
Aside from my first relationship, I've never been dependent on the other person for anything, maybe that is your problem?
