[Daring Scylla]

It's kinda like when someone says 'Don't turn around" and you do anyway, eh? The more you try to avoid thoughts of her the more they will come back.
So accept them. Say "yeah she's there I know, but I'm just going to look away"
I have someone I have a similar relationship with, except this person wants nothing to do with me now that I've told my feelings. They'll talk to me and be nice, but I'm not allowed to hug them or talk about certain things to them....everything reminds me of this person, but I just sort of accept it and move on, and try to distract myself in any way possible. I hope that can work for you too.
