This is why the "Friendzone" is both a myth and also ridiculous. You can't be "put" in it, you choose whether to remain friends with someone (or force a friendship because they won't date you) or not after they reject you (assuming you actually tell them you want more than friendship). So since you didn't want friendship, but she only offers friendship, then don't be her friend if you don't want to be that close to her while you only get hurt seeing her give what you wanted to someone else. You can have other friends, you don't need to be friends with someone who rejected you, because as you know, you want more and that places unfair expectations on her, and you know she doesn't want more, but she takes advantage of your feelings and uses you for companionship and friendship, knowing full-well it hurts your feelings to see her with someone else.1THIS IS NOT RELEVANT ANYMORE

Look at it this way you may have not progressed further into a relationship with her - but you at the end of the day don't leave with nothing since you clearly have a good female friend which is a good asset. She clearly still sees you as a great friend since she still wants to hang out with you and spend time around you.
I would highly recommend you try to move on away from her if possible. I don't honestly see a relationship being viable between both of you.
However, a positive of having female friends is sometimes they hook you up with others like in my case. I was hooked up with my female friends best friend and it worked out great and unexpected. Female friends are valuable due to this so it's well worth remaining her friend.1THIS IS NOT RELEVANT ANYMORE
