My ex and she was the one who left me want to be friends again

She was the one who said she doesn't want me anymore and the ending of the relationship was kinda toxic and I tried so many times to get her back but she refused then when I finally give up and let her go and wished her the best in life and wtvr and removed her, she blocked me but it's fine. but after a month she come back to check on me and it was sweet and fine then she followed me the we kept talking normally for some days and when I told her about my feelings and If she wanna try again or not she said we can be friends nothing more but what kind of friends who block the other person on all platforms and phone numbers expect Instagram?
