OK so first, above all else thank you for this post. I assure you I've read it all, now let me try and answer as best as I can.
I actually did make my interest known from the beginning. 2nd day after she arrived I was all over her. Stroking her, pulling her close by the waist, lots of kino. Didn't think it was the right thing to kiss, but I probably should have I suppose.
It's the second party, the night when she hugged me randomly as I was sitting on a chair, that she told me she didn't want to get attached. So between that night and Friday night, there have been IOIs, and you're right, why would she
show these IOIs only to for me to find out from someone else that she doesn't want something with a flatmate.
I'm sure she knows that I want her sexually.
Like even tonight, she put her hands on my shoulders to pass me (I admit this isn't much at all), but whenever we made eye contact she would hold and look down.
That's why I think this advice from
@samspade is great " My advice is
take it in stride, put it on the back burner, and find ways to DHV and get her to qualify herself.
But above all else know that if you manage yourself well, these things have a way of happening. "
I will keep you up to date.
