How do I be friends with this girl?

[FireballKid27]

I was talking to my former crush (I confessed my feelings to her a while back and she said that it was sweet if me and that we should keep in touch). We were having a nice conversation on Facebook. The problem was that sometimes she would take 2-3 days to respond. So now I messaged her back and she hasn't messaged me back. It says that she has seen the message. What does this mean? What do I do now? I'm afraid she won't message me back
I just want to be friends with her. Should I ask hey to hangout or visit her? ADVICE FROM THE LADIES WOULD HELP A BUNCH!!!

She's not worth being friends with.

She is playing you or pushing you away. If she cared a lot she would have written you back. She isn't interested in being friends.

Calm down. If she doesn't ever message you back, it's not the end of the world. You'd just have to move on. From what you've said, it seems that she probably doesn't have romantic feelings for you and only sees you as a friend. If you try too hard to be her friend, it's only going to push her away even more. Let it happen naturally. Don't force it.
