Well, getting really off topic here. Then again, others are talking about flipping skirts at Catholic school ... so
Hey, I don't mind vearing off in different directions, religious or not.
Unconditional love comes up quite a bit in relationships that are experiencing imbalances.
Unconditional love creates monsters, IMO, and entitled princes and princesses who never get challenged about their base presumption that they do indeed sit in Corri's Seat of the Universe Chair (TM).
Oddly enough, those individuals who insist that you should love THEM unconditionally, come with a boatload of conditions with which YOU must comply before they will dribble a bit of kindness your way.
Human nature (ours and theirs) compels us to interact with each other with conditions. It may be that the only condition we can enact is "if this situation continues, I will have to disengage myself from it".
Unconditional love is a myth, IMO. For ex., if any of our spouses began torturing our children or pets, most of us would quickly find that we DO have conditions. It's merely a matter of where the lines of condition are drawn.
