Thanks for your post. It definitely gave me something to think about.
My thoughts on the issue is that, of course, it depends on the people, the place. The odds of my meeting someone where I live who knows about female led relationships are slim but it would be possible to have a relationship mirroring one, just without the label. In that case, it would depend a lot on temperaments and like you said “sending out signals”.
Sometimes I think I get too bogged down with the labels and the logistics of what an FLR is that I forget it is a relationship and not always clean and tidy, in FLR terms. So I wonder if it might be best (for me) to focus on finding the characteristics I’m looking for with or without the label.
