I believe I can love infinite people. That said, I also have limited time in my days. I need to be cognizant of that. Pengrah has specific needs due to health which take up time. Anyone coming in has to recognize that as well.
I have also discovered I enjoy focus. If I am entering into a new romantic relationship I can't bring in anyone else. I have a stable loving relationship with my wife, however need to ensure anything new is being focussed on one. I believe, in my case, it would be unfair to all parties involved if I tried to stretch that too thin.
