This was brought to mind by a case I read about which actually happened almost 30 years ago now but where her killers were only found guilty last year. It was in the 90's a young girl had a crush on a boy in school and he told her he wanted to meet her one night. So she went only to be met with him and two of his friends where they beat her unconscious and either threw her or let her fall into a river where she drowned.
It made me think of when I was that age and possibly even older where I would like particular guys who looking back were not nice or decent people, not men I would have actually liked if I had went out with them and a few I found I didn't much like when I did go out with them, even those who would not have been violent were probably still not good men, addiction issues were rife and even when I got out of the housing estate I grew up on and went to uni many nice middle class boys also seemed to have addiction issues, wanted to sleep with and discard as many girls as possible.
At that age though often we like them without giving too much thought to who they really are we want to be accepted, loved, included, to belong and to know who we are or will be and I think attraction is tied up in all that uncertainty when you are young. I can even be the same with friends you don't really see them fully until your need dampens down a bit.
I suppose I was lucky in that I did meet my now DH and being with someone who I did actually like as well as fancy and love and who felt that way about me was like night and day to my other experiences.
