I've known this girl for the better part of 3 months now and have been spinning her since the 1st week. Recently things have been getting serious and in that time I seriously considered turning this into an LTR.

She's on winter break from school right now, as am I. 2 days ago she suggested we Skype because she missed me, I had plans so i told her the next day and set up a time. During that conversation she suggested that we become exclusive to each other and I agreed. She's extremely good looking, smart, funny and the sex is among the best I have ever had.

Fast forward to today, she somehow finds my instagram and adds me, so obviously I look through her stuff on there just to see if I can find any red flags. I found one, she's been hanging out with her ex bf quite a bit while she's been home and hasn't said a word to me about it. The most recently being 3ish days ago, but who knows

Im not comfortable with that at all if I'm entering an LTR with this girl. Should I confront her about it and say that shit isn't gonna fly with me or wait until after we get back from break and say something?

Confronting her now would probably happen over the phone or text but obviously texting this is a shitty idea.

Or nuclear option and end it and move on?

Your opinions are welcome.
