Thoughts on behaviour and morales

I was thinking about the women that I "hang around" with from time to time who I have come to know since living in this city. The thinking starts with my friend, who I've known since my oldest son was a baby, as her son was born 3 weeks before him. We were quite close friends for the first couple years and it seems to me that the more I got to know her, the more I didn't like her and her choices. Now, what gives me the right to judge, I guess is the question. But I think my problem is the fact that I have morales and increasingly, I see women having no morales. I don't know what the trend is or why this is happening but it seems to be true.
This friend of mine has willingly gone to the bar to find a man to sleep with and done so. She's been with countless amounts of men and has no shame. She has no qualms about smoking weed around her son (who she rarely has anyways) and had no qualms about doing coke for the longest time either. She just doesn't care. She doesn't think about what she does and is only interested in herself. She doesn't want to be with anyone for a long period of time and has no shame in saying so.
All her friends are just like that too. I don't understand what it is that makes these people happy. One of the girls has lost her son and refused to stay with the father. She repeatedly cheated on him and wouldn't stop. She just didn't care. She had no morales and just did what felt good to her. She would have men over while the father was at work.
It's like pleasure and disregard for anyone except themself is the crack cocaine of society today.
So many of the women I know are like this. Am I missing something? Where are all the good people hiding? I mean, sure, I don't get out much but what the hell is going on? I'm sure there must be some good women. Maybe they're hiding in the churches or something but then they're going to be judgemental and religious. Mind you, smaller price to pay than the chances of catching some STD or getting sick from drugs or who knows what else.
I'm not saying I'm perfect. I drink on the weekends. I've made mistakes with guys and had sex too quickly and then found out they weren't interested in anything long term. I've dated a married man (which is the worst thing in the world I've ever done. I fell in love with him before I found out and then I couldn't stop). But I try to be good. I put my children first. I'm looking for long-term and nothing less. I'm devoted and loyal. I'm respectful and honest. Why are those things so hard to find in other women?
Don't women realize that by behaving like this, nobody is going to want them? They just look cheap, dirty, used. Or does it even matter anymore. I guess girls like that, find guys that like that. I'd just like to find a girl that's not like that to actually be friends with. Heaven forbid, find a guy who's not like that and is a good match for me. *sigh*
