Really sad

Tryied to help out a friend who's couple I think may have NPD, or very strong traits.
When I first started learning I sort of obsessed about NPD and researched all I could. I told her about my "findings" but when I started seeing she needed help I droped the subject and focused on her. Didn't want to project anything that did not belong to her. I was kind of was afraid that the obsession started to reach people that didn't even have NPD, and didn't want to cause any damage.

Time passed, she seemed to be doing well, and this saturday got a phone call, she sounded really down. I wont tell you the nature of his behaviour, but basically he has been an ass and she was afraid he would carry on doing that.

This monday I sort of told her that she needed to focus on loving herself more than him. She said she was fine, confident and everything. She didn't like what I told her. She told me she needed him in her life. So today, I sent her some information on psychopaths and she got really angry. That it was her choice, that I talked about NPD all the time (not true I havent honestly said anything to her about that in little over a month, and haven't spoken that much either), that she was very upset I saw him as a psychopath. I tried to explain that it's not that he's a psycho, but that all psychos are N's but not vice versa. Couldn't finish. She logged off.

I'm kind of worried I did something wrong; is it me?? I just wish someone had told me the things I told her. Told me "investigate!! you're a scientist, check out just in case". Just don't want her to be through what I've been thorugh. Did I cross some sort of line?? I'm not very good with people, afraid I performed major screwup with friend.

Hugs to all,
