Why did she say that?

She's probably testing you

Well how many relationships have you had? Maybe she wants you to be sure you have " sewed all your oats" so you don't have any regrets with her. Could she of been in a relationship before that ended because the guy wasn't ready for a relationship?

When I read your post, I was thinking that maybe one or both of you might be a little inflexible when it comes to meeting each other half way. Maybe she wants a guy who just goes along with whatever decisions she wants to make in life, or possibly you are that way?

Another thing I thought of was her telling you to date other people, how many have to dated before? Maybe you are with her, but you don't really know why? Knowing what qualities we like in prospective mates is something good to know. Perhaps if she asked you what you liked about her, and you couldn't really put a finger on it, she became a little hesitant about your relationship.

The best thing to do, if you are still together, is to talk things through with her. If both are into one another, you should communicate. It would be sad to let things fall apart by just guessing it to death.

Good luck!

Either that she's completely confused to give such different statements, one straight after the other, or that she means you're not ready for something with her. Maybe she thinks you're afraid of commitment and wonders where your relationship is going with her. She may be feeling tired and frustrated with uncertainty that she may be feeling from you, real or perceived.

My opinion, she likes you and she doesn't just want another relationship she wants something more she wants it to last and maybe she just want you to date other girls and see how you feel or see how a relationship work!
