When a thought comes to mind - any thought at all which questions the safety of loving said person - you might decide to believe the thought and withdraw your love, and “this” is what hurts, really hurts. 

Too much conditional love. Too much staying in bad situations because you’ve learnt unconventional conditioning. Love and leave them if you must. If you’re loving, you’re fine. People will come and dance under that light of love, and then they’ll leave that light of love, and none of it will really matter, my love.
