She added her ex back on snap a couple nights ago while i was with her, she had ghosted him a little bit before we started dating and sometimes talks about how he was good to her (unlike most of her exes). She texted me and told me she had added him back when she was in the bathroom, I asked her what she'd said to him and she had apologized for ghosting him, and told him she was focusing on school, finding a job, etc. 

She then had been messaging him for most of the night while I had headphones on and it was kinda tearing me apart. When she came to bed to cuddle we talked about it and I ended up crying to her about it and she brought up my ex who'd very blatantly taken advantage of me. Saying she wouldn't do what I did w him. 

I also forgot to mention that she called him hot while showing me a photo of him. :/
