To avoid being dragged into court, I'll put the disclaimer first. I have no affiliation with, nor do I make any representations regarding the views held by anyone I reference in this missive.... and I am not a lawyer (thankfully)...
In regards to relationships in the 21st century I have only ONE thing to say to any male seeking female companionship..... "caveat emptor".
Why ? Have a look into what has happened to "equality" in the context of Family Courts around the globe. Stuck for somewhere to start? Try the books and videos by one Helen Smith.
Otherwise, "have a nice day".
