I think she answered your question with her not wanting a boyfriend at the moment. She just wants a friend she can hang out with and that COULD change (to keep you hanging on and following her). Rarely does that happen though. Good for you for being open and honest although some people cannot always handle that approach. If she lost interest though, there isn't much to do about that.
Don't get carried away with it. It may feel like the world is just shitting on you to pile up another dissapointment so very soon after getting your world turned upside down after the break up. This doesn't take anything away from you and who you are as a person. I just don't think you are 100 percent available right now and it's a bad time for you, if not for her as well. It takes some serious time after a break up, especially if its your first, to really get yourself back to normal and it's a lonely, miserable existence when you don't have somebody else there to help take the pain away. It's just very difficult when you are still emotionally wrapped up. Take a little break from the dating scene if you just don't feel into it and have some fun with your friends and get you back up to that person you used to be pre-breakup. Or if you feel like you can handle it, try dating somebody else.
Everything is going to work out alright in the end even if it seems like nothing could get worse right now. It takes some work and effort on your part to get yourself out there and put some time in taking care of yourself and increase your attractiveness, so if you are sulking and wallowing in self pity, stop it.
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
