Girls help... she doesn't know how she loves me

Here's an answer to your last question -- yes she's afraid. Not necessarily of falling in love, but falling in love and getting hurt by her best friend who's known about her in and outs with men and the latest details with her friend, Missy, down the street. I think she's also probably afraid of ruining what a great friendship you all have together if things don't work out romantically between the two of you. My advice? Do as she asks...back off with the "yucky love stuff" for now and let her heal from the relationship she just got out of since it was a rough break up-- there isn't anything you can do to prove to her that you love her or won't hurt her -- what she needs right now is time to heal her heart and her head. Do be weary as a friend too...since you've told her how you felt, at one point in time during the healing process, she could feel lonely -- and she might run to you knowing that you care, hence possibly giving you, and her the wrong idea and in the long wrong hurting both of your hearts as well as your friendship.

None the less, chin up and I wouldn't give up on someone you love, just give her time to work through the confusion she's feeling right now, without the added confusion of another man.
Good Luck!!
