Bad Boys vs Nice Guys

A regular debate I have with my friends (married/attached/dating/single ) is around the love of a bad boy. I am guilty of my back catalogue of men containing 90% complete players. I am all about a passionate relationship, but someone very wise once said to me that 'with the highs come the lows'...so in order to experience that euphoric feeling of a passionate relationship you have to be prepared to also tolerate the downs of the emotional roller coaster. But some women don't look for this passion (the majority are the ones who currently settled with 2.4 children)...... They are content with their lot....A steady man who treats them nicely but doesn't rock their world. Is this settling? Or is this called growing up and realising that after the lust and passion leaves the relationship, all you are left with are the 'downs'.....? Is it then better to look for that man who doesn't give you excitement and passion, but also doesn't hurt you on purpose? The jury's still out.......
