Well I think the concept of Love is not what it use to be. But one thing I like is religion isn't repressing relationships any more thank god.
But personally I think either is a good way to go, GF for those who want to spend time with each other and devoted relationship. FwB's for those who want more variety, and to get more flavors haha. Personally I may lean more towards FwB's.
Always gotta have a sideline xD
