First time posting here decided to give it a shot. So my girlfriend face timed me while she was away at a camp (she's 18) asking me what I've been up to and all that stuff. However she brings up a topic and starts talking about how she's "young" and wants "live" by drinking and smoking weed stuff like that. I played it off cool, at the same time I'm laughing, I call her out for needing drugs and alcohol to feel alive calling her lame. So we keep talking and she brings up how's she's been going skinny dipping with her friend almost every night at this camp. At first I thought ok that's kind of odd, but I didn't say anything I just ignored it and said "that's cool". I then realized before she went to camp, she had told about the skinny dipping and how she goes with her friends and other guys there too. I don't know if she said she's been skinny dipping during our FaceTime to make me jealous? At the same time she brought how I don't double text or I take a long ass time to respond to her I said nothing just that I've been busy with work and working out. What do you guys think? Are there some red flags and if so, what should I do? I'm leaving to college soon and she's going to be a senior in high school, is it worth pursuing an LTR like this in college?
