Etoille, sorry, but terrible, terrible advice with the ramen bullshit. Women are great for some things but "how to get the girl" is not one of them. They envision ultra romantic grand gestures that in reality make girls weirded out when it actually happens, because they are thinking of Disney movies and the man in question fighting evil dragons to rescue them.
Women are amazing for interpreting responses. Pointing out that no girl interested in a platonic friend will be contacting you so often, that is good. And for some other things too. One of my female friends asked me if I invited DG to my bday, and I said no because I knew she couldn"t come. That"s male thinking. She told me I should invite her even if I know she can"t come. Took me 1/2 second to know that she was right. She saved my ass.
Anyway, Tarrant I"m with you on this particular case. I think you are on the right track. There is a world of difference between "lets just be friends" and "we need to stay friends for right now" with the very clear unstated desire to escalate when the time is right, while calling you all the time and wanting to stay the night. Obviously, this could be all for nothing and she comes to see you as a pushover and get friended, but handling this situation the proper way, which is what you are clearly doing, generally avoids that outcome. That"s a risk you are aware of though and have clearly accepted as a possible outcome.
This isn"t a standard send-the-package like situation. None of this says "I"m a desperate guy I will do anything for your love." Obviously there"s not much advice to give and you know you"re on the right track, but doubt from even strangers does often unconsciously make us doubt ourselves, so I"m here to lend a supporting word, haha.
Are you able to make a move yourself? The physicality seems all initiated by her, but if you can take charge sexually without alienating her or making her feel rushed I"d suggest you do it on Sunday. I can"t tell if the situation warrants it though.
