Surely it is not true that anyone can become a lover/partner with anyone else, and that being the case then whilst I agree you can be happy with more than one, you still need to find one whose soul talks the same language as your soul!!
But everyone thinks religion, politics (pretty much another religion) and wealth are needed. Lol. Getting rid of all of these things means accepting personal accountability and responsibility and nobody wants to put in that kind of effort for themselves or the rest of humanity.
