Darn, I wish I had some advice, but unfortunately one of my 'handicaps' is not being able to give proper advice besides cliche ones - what am I talking about, probably over 50% of my attitude&vocabulary in social situations is taken from someone else, including movies, books, etc.
All I can say is I relate to a big part of the things you wrote up there. I remember last time I dated a NT; it was uncomfortable, mostly. Why are girls always expect to hear "I love you"? If I don't feel that way, why are they forcing me to lie? Also, physical contact in certain zones of my body, feelings needing to be expressed, phone calls, etc. it's all too exhausting
