<human>: Im not certain if I'm posting in the correct sub, but I want to ask what your guys opinion is on this. 

I have kept a friendship with someone I met roughly six years ago through social media. Let's call her Lady. We were both in a relationship back then but recently we decided to catch up. Instant connection. We began to be intimate as we began to get to know each other on a much more personal level. We both accept we are only dating and not in a relationship, but something I recently found out troubled me and I confronted her about it. 

As I have told her, I know we aren't in a relationship and even if we were, I have no right to control her actions or who her friends are. I found out she she is still seeing a guy who she was a sexual partner with weeks before me. That part doesn't disturb and I do not want to make an assumption she is sexually active with him. Also because I don't have knowledge of their past or friendship. What disturbs me more is that she does various types of drugs and narcotics with him. She does more than weed and shrooms, I never got the full details of all she does and I don't think I would want to know. See the problem is this conflicts with my morality, because I wouldn't want her to be the mother of my children with that morality to raise them, not to mention she is putting herself in an unhealthy situation.  

We got into a argument because I told her simply it makes me uncomfortable she does this. I've offered to help but that only made matters worse. I've also realized I can't fix people nor am I saying she needs fixing. It simply conflicts with my morality and attraction in a woman. Looks currently as though our friendship is coming to an end. Reddit, am I wrong for being bothered? Am I wrong for letting her choose that lifestyle instead of imposing on giving her help? I offered but it made matters worse.

Can you give me the gist of the text in a nutshell?
