So today in the morning I clicked on my gf's phone to check the time and saw a text from someone she used to hook up with.  Usually wouldn't care, but text said something along the lines of "hope you liked my snapchat ;) ;)"  I was curious, and even though I shouldn't have looked at their conversation.  Leading up to his text he brought up his penis and although she said hey now calm down I have a bf, she still flirted and complimented his penis.  Then said we just have to be freinds if anything.  I didn't see the snapchat, but she had yet to respond to his snapchat text although she did open the snap I guess yesterday.  If it was something sexual like I suspect, she should have definitely texted him when she opened it that that was not OK and that they could no longer be friends if that was what he wanted.  She didn't do that, just left it blank.  That is what worries me, because I know my gf is fairly attractive and is going to get hit on, but I need to know that she'll set boundaries and let ppl know whats not ok.  I'm planning to bring it up to her tonight, by just asking her to see her phone and asking her why she felt the need to have this conversation (especially the flirting and the complimenting) b/c she should not have led him on at all, she should've stopped it when it became sexual.  I'm planning to prefacing by letting her know that I'm not proud that I checked her phone, but was also really thrown off by the text, and would understand if this is the end of the relationship.  I don't know if that is to dramatic, what do y'all think? Am I in the right for bringing it up or should i let it go?

Thanks fellow redditors.
