Might not be the right sub for this but...

This is a bit complicated.

He obviously is grooming you and wants sex in exchange of getting you into medical school.

In an ideal world, as soon as you realize this, you should cut him off and find another doctor to shadow. But doing that requires a force of character and knowing that you can get into med school (may not be your dream one) without his help.

Now if you don't cut him off and hope he will still help you without giving him what he wants you will be gambling with your med school application. I'm assuming you intended to ask him to provide an LOR. Are you sure you want a man you turned down to write you a LOR ?

If I were in your shoes, I would decline any informal meeting. Make excuses: 'I will be seeing my boyfriend. I am with my stepmom'.

Then, pay attention to his behavior. Naturally he will become less kind and harsher towards you. If this is what happens, you really don't want him to submit an LOR for you. That means you need to find another doctor to shadow.

Your post reminded me of Harvey Weinstein.
