<human>: Can you provide a brief overview of the text?

Hello, I [19F], have a best friend [21M], who I fell -and am still slightly in / feel I will always be- deeply in love with. I know he doesn't like me that way, and I have been trying for about half a year now to just move on. I even go on dates, but most of the guys I go out with I legitimately can't see dating, and even if I find a nice guy, I will question if I 'want this' or if i am using people as a distractions from my all-still-there heartbreak. I'm considering saying I'm just not ready to try dating anyone, but besides this one friend I have no one in my life to go to, and genuinely want someone I can trust and be comforted by. 
*side note* He has recently started dating this girl, who I like and all, but I break down to where I can rarely ever talk to him without tearing up a bit, and I know it's very annoying and hate myself for it.
<bot>: My question for advice is how can I know that I am not just using people, to avoid heartbreak. Also maybe I'm doing this whole getting over it thing wrong- any advice?
