I am finding that the more love I give the more I get in return.
I've always had the opinion that I'd rather have one really good friend than 20 people who were only around when they thought it would benefit them.
To my mind it's similar to the church tithing. You give to the church and God gives back to you. I give my love freely, without expectation, and I receive it back many times over. Maybe not right then but on down the road when I might need it more than I do right now.
There are as many ways to do polyamory as there are people practicing it!
