Why is it when a new relationship starts and you feel entirely in control (ie, NSA or similar, no future in it) and enjoy it for what it is initially, then a few weeks or even months down the line you realise with horror that feelings have strongly developed and you have no control whatsoever, in fact were only kidding yourself that you ever had? And then heartbreak of course closely follows. Is it mainly females who need the emotional attachment, and how can one recover or learn from this experience?
