I'm a decently popular guy in high school. This takes place about 3-4 weeks ago. My girlfriend was beautiful, popular, funny, and the most impressive of all, she put up with my jokes. I was out on a date with her, we were seeing a movie and going to dinner. After dinner, I was hanging out at her house and I got a text from a girl I've been friends with since we came out of the womb. She told be that she needed help, and I knew that she was going through bad depression problems, so I left and drove over there. My girlfriend got mad at me for leaving in the middle of something, and I promised I'd be back after. When I got to my friend's house, I don't even remember what she needed, but it was nothing important. I checked my phone after I helped her, and my girlfriend was getting increasingly mad at how I continuously put friends in front of her, which I admittedly do, and told her that it was because no girlfriend could mean as much to me as a friend (in a much more blunt and poorly worded way.) She didnt respond, but I didn't notice because I was already heading back. When I got to her house, I walked in and went to to her room and saw her with a gun in her hands. I freaked out and ended up talking to her for about 6 hours. She's fine mentally and has a more accommodating boyfriend now, but I can't stop thinking about how I nearly caused a death. Am I a dick?

I have been friends with a girl for as long as I can remember, and since we've arrived in high school, she's a little insecure. I'm usually her go-to guy when she needs advice or has to be talked off of a ledge. She's started dating a guy who I know and he only ever sticks around in a relationship long enough to put his stick around in his partner if you know what I'm saying. My friend really likes him and I'm terrified that she'll do something extreme when he breaks up with her. How do I handle this?
