It's that she was cheating on her boyfriend that produces a negative reaction toward Ashley from some of us who are a bit old-fashioned.
Cheating on a boyfriend/lover/spouse may rub you the wrong way. It's not something I would do/have done but in some cultures it is almost a way of life. Italy and France, for instance have a long history of being quite accepting of such things.
My Dad, born in 1952, was the product of an awful marriage and my Grandmother had an affair with my Grandfather's best friend.
My mom was still married to my bio dad when she met my stepdad. In 1981ish.
Affairs, love problems are nothing new and I think unless it's directly involving you, it's unfair to judge. To be quite honest, there are likely more affairs going on around anyone than most people realize.
Cheating/mistresses/love triangles have been around as long as humans have existed and will continue until we are gone.
There is no reason to think negatively because she/he may or may not have been cheating. Some articles say she and her boyfriend had broken up. Perhaps it was just a fling while on a break from her boyfriend. At any rate, a very wise man once said, "Let he who is without sin throw the first stone."...The townspeople walked away, laying their stones in the dirt because no one could call themselves sinless.
Plainly, if she was having an orgy every night her boyfriend was away or some more "outrageous" actions, nothing would justify her murder. Not at the hands of her boyfriend, nor any other.....
She had the right to live, whether we agree with her actions or not. I pray for her and her family, as well as her boyfriend. Heck, I'll add in the murderer's family because as far as we know, they are not culpable in this either [their son/brother/nephew is also gone to them]. They've all lost a beautiful person, whether she slept around and did drugs or was a saintly woman on Earth. Murder is not justified in any case. It is sick. Throw the book at him but leave the victim and those who surround the case with a sense of peace.
