Scripture does not condemn that as sin as far as I can tell. I don’t recall ever reading anything alluding to that.
And yes, our society is filled with sore, or perhaps better, toxic relationships and I can understand the desire to want to avoid them.
The number of truly healthy relationships I have seen in my life is pretty small and seems to be dwindling these days as godlessness abounds.
“Scripture does not condemn that as far as I can tell.”
Seriously? I think StPaul had a thought about that !
