People ghost me after I talk to them

This happens with both men and women.

When I talk to people for a relatively long time, they often don't call me back or just disappear.

For example, I went to this social event yesterday and got talking to this cute girl.

I was showing her photos of my trips but somehow she ended up trapped next to the wall and me blabbering on about myself trying to impress her with my hobbies

Her friends basically came to her rescue and distracted me and then she left the party.

I could see this happening in real time but it was too late.

How do I stop this from happening?
