Is AUTHOR wrong in the post ? POST : First time poster, long time reader 

Bit of background info: I'm a doctor working in ER (Emergency Room) and as you can imagine it is busy at the best of times. It is hard to maintain a social life and go out to meet people. 

A while ago, I treated a patient who had a benign condition (was discharged within 3 hours). Lets call her Sally. There was a bit of waiting time for lab tests and etc, so Sally and her young son were getting a bit impatient. I built some rapport with the two by playing with the kid (making balloon animals using gloves etc). All the tests were fine and she left with some paperwork which always has details of the treating doctor.

A few days later, Sally contacted me on instagram (she found my profile by the details of the letter) and basically said she was interested in me. I obliged and we went out on a few dates. Fast forward to about a week ago, we had been dating for 3 months. I had grown to really care for her child and I was falling in love with her. I finally introduced her to my family and told them the truth about how we met. Even though they really liked her, they were completely against the idea of us dating given how we met. My parents sat me down and explained why it was wrong and convinced me to call off the relationship.

After struggling with their advice and the feelings I had for my girlfriend I finally made the decision to break up with her. I'm miserable but I think ive done the right thing. Since then my phone has blown up with missed calls and texts. Sally's sister has messaged me saying that I took advantage of her and forced her into dating me even though this is completely untrue. 

I cant help but feel that I shouldn't have broken up with her. I can understand why people would thing its unethical to date former patients, but im feeling really conflicted.

So reddit, AITA??
