This is really bothering me.

I have an huge crush on my best friend , I’ve only known her for over an year but she’s my best friend because we have an close friendship connection. Like really close. That close we do double dances and wear matching outfits and have photo shoots together in our lingerie , we tell each other everything. I told her I have an crush on her but she said last week I wasn’t her type because I’m too skinny. I deleted Instagram to give her space and to cope with being rejected as it really hurt me badly but I wanted to respect her decision because I really appreciate our friendship , I then had no choice but to text her because she’s the only one who could help me with an certain thing , she was upset and worried because she thought I had fell out with her and thought I deleted Instagram because of her. I can’t really win. She was on about it last night , she was upset when I told her I did it to give her space. I also decided to try to stay away from her as we did get really into each other’s personal space but I couldn’t because she kept asking me to follow her Everywhere and sit with her so I did. She sat extremely close to me nearly on my lap , she then taken me downstairs and taken bdsm photos with me , she kissed me on my cheek too but she also pulled out tinder to look for other girls whilst I was sat with her. I don’t really understand what’s going through her mind , it’s extremely confusing , she made it clear verbally she has no sexual or romantic feelings for me , I’m trying my best not to make her feel like I’m an stalker or creep or obsessed with her but if I don’t give her attention she thinks I’ve fell out with her or she’s upset me.
