If she has boyfriend and she is that good of a friend to you- why haven’t you met him yet? He is long distance? Have you even seen a picture? She should talk about him if he means that much to her. I am an old lady, and I feel, if they are not having *** on a regular basis - what kind of relationship is that even? You have to open up to her and tell her you would like to be more than just a friend. If she still rejects you as a potential bf or lover, you have your closure to move on. You shouldn’t stop being friends with her, but can you handle that? You seem young. This will pass. You have time to find the one.
