But were you in a relationship? By "courting" I assume the getting to know/feeling out compatibility stage, not an actual full blown relationship.
I don't ghost people I actually know well. I send a "this isn't going to work because of" and list the reasons then if they are drama causers block everywhere. If not drama causers, no need to block. We can just move on.
Assuming that my very serious desire to avoid drama and my very valid point that A LOT of men argue when told no is because of some trauma is ridiculous. It was just watching and learning/trial and error to see what works for me. I tried the whole letting people down easy thing and more often than not it led to drama. So I don't do it unless it's a pretty serious cut off. Many, many, many women can share multiple stories of men blowing up and making them feel uncomfortable, unsafe, or worse after being rejected. Good for you for not being like that, but don't let that diminish legitimate experiences. I've never felt unsafe or anything, just pissed that dudes try to be manipulative or rude.
I had a friend who I cut out of my life despite loving her deeply. She was a drug addict though and I just couldn't watch her hurt herself anymore. She wasn't ready to change yet. I told her all of that. That I loved her but couldn't be in her life anymore at this point. She was not a dramatic person so she just apologized (not that she needed to - she was an addict, not abusive or bad in any way) and we both moved on. She got clean after we had moved to other sides of the country and sent me a message THANKING me for cutting her off. Believe it or not, my personality can be healthy and helpful at times. Lol
I'm not afraid of closeness at all, but I have no desire to foster artificial closeness with people I don't actually relate/connect to. I have my two partners that know literally everything possible about me, and I know quite a lot about them. Other people confide in me at times, and while I'm happy to be a support it doesn't mean I'm going to reciprocate by sharing about myself unless I want to. Their openness doesn't mean I owe them anything. Just like you sharing your emotional baggage didn't mean she owed you more contact.
Obviously people's experiences shape how they handle life, but it doesn't always mean trauma or immaturity or any of the things you seem to want to blame. Sometimes people just aren't interested and aren't interested in expending more energy than necessary on ending flirtations.
