mmm..
I rarely bother with typing on here these days, its all FR and lay reports for me hehe... But whatever ill give you a hand.
First of all dude, after this advice im going to need a free subscription of aspirin for the headache caused by reading your plea for help lol

k, your not pulling the trigger. But i think the real problem is that your coming off as way to needy! you keep asking her for 'her opinion'. Yeh you do it once to open, as a offhanded canned opener, but if you keep doing it lol.. she will start to think, 'is this guy social at all?'. I have no clue as to what type of sexual energy your putting out with your body language, my best guess is that your fairly nervous and jittery in the set.
You need to demonstrate some higher value, you are a doctor right, she is a nurse right? well.. start acting your role buddy! I don’t mean talk rubbish about analytical nonsense with her. I simply mean demonstrate a authority over her world, act alpha. I want you to tell her she looks sexxy!I strongly believe shes confused as to your intent, and your going off into a area where you probably don’t want to end up. You need SOI sadly.
And when she knows your intent, DHV again and then go into creating a emotional connection.
The incident with the number where she didn't text you. Basically you seemed way to keen. And she kinda jumped back. Thats called a IOD. You need to create more of a fun frame with her. Drop your objective and work on making attraction dude. Its more important than her and your shag issues. if you make her feel attraction that won't even be a issue.
Oh and another thing, you dont NEED anything, youd like something. Make sure you come from that angle always.
Kind regards,
best wishes
