Should I remove her from my friendlist?

We are living in different countries and I had a crush on her for a long time, over half a year could say.. I did tell her how I felt and she said "I dont know what to say" bust she still kept saying stuff what usually someone says when they are interested so I was really confused, well now she met a guy from her country and well I'm quite jealous about it but I still accepted it that I'm not the one and I'm very mature about it, but it still makes me quite depressed and I'm tired of the pain so I want to unfriend her, but she's very lonely and depressed irl and many people has left her so I dont know what to do because we still have become fairly good friends but I want the pain go away. Does anyone have any good advice I would appreciate it a lot.
