Context: I'm in a LTR with a girl, we have to be in a LDR for about 3 weeks so that's the current situation. Last night I was skyping her and we were just talking, then my phone vibrates. Two snapchats from my friend (male). I don't open them and continue talking. Again, another two snapchats from another male friend. She hears the buzzing and

Her: "who's texting you?" Me: "Just my friend "M"" Her: "uh huh...probably some girl" Me: "I already said who it is, I'm not going to argue with you, that's the end of this" Her: "whatever, I have to go to bed"

She hung up on me then called me back, I missed the call cause I was in the bathroom. I called back but no response. I don't plan on talking to her until she reaches out to me.

I know this was a shit test, but I'm not entirely sure I handled correctly. In retrospect, I would've A&A since she would get mad anyways. Willing to provide more context, if needed. My question's are:

How should I have handled it better? Why did she react that way? What should be said when she comes back? What other advice do you have?
