Don't send her anything else. It's pointless to send messages like that... it can come off as slightly desperate and like you can't let go. I'm sure she is perfectly aware of the situation and whether to contact you or so no need to do anything else especially if she hasn't replied!

Did she indicate that she wanted to be friends with you? If so, then you haven't created a power shift yet by rejecting her platonic relationship. When a woman says that she just wants to be friends, it's more along the lines of "Hey, I want to feel less guilty and still keep you around so I don't feel as bad. I'll keep you as my friend just in case things go south with my new partner, and use you as backup". That's why it's critical to reject her friendship so that she has something to lose. If you don't want to rekindle things with her, then you could say it and just never look back. If you're looking to rekindle things, then you have to let her come to you, and she's the only one that can determine if she wants to get back together with you. Use the time apart to better yourself and look for other women. It's usually when you have completely moved on when they come running back, and you probably would have found something better at that point.
