Me and my friend like the same guy

She had a friendly relationship with him, not really friends, but more like acquaintances with mutual respect. I didn’t really know him that well, but i’ve recently started being in the same vicinity as him quite often and i’ve grown to really like him, for like over a month now. I wear my heart on my sleeve and even though i never out right say i liked this guy, i know my friend realized. She’s always respected him, but recently started talking about if she likes him or not and now shes saying she does. Ive never liked a guy before, while she has, often. Im kind of upset that she knew i liked him and started talking about all this around me. It makes me uncomfortable and sad and i know she realizes. She doesnt usually behave this way, so im confused and overall really upset over the whole situation. Im also mad at myself i never told her i liked him, so now that others know she likes him i dont want to look like a bad friend. She even told me to “give him to her” and not to get with him, which was weird. (At the end of the day obviously it matter who he likes) i feel awkward if i get any close to him now, because i dont want to look like a slut, but i also dont want to keep my distance, because i really really really like him. I dont know what to do
