I think it is because they cared for you. I see two perspectives
One is that you are a very confident traveler by yourself and know exactly what you are doing. Not many woman can do that. Kudos to you.
The other perspective as an outsider ( a friend or a relative,) they care for you.
After a certain age or when we are unable to do certain things by ourselves we need support.
My suggestion is that when you embrace both the perspectives you can lead a more empowering and collaborative life.
