So after all of it happened, I ended up hooking up with this Friends with Benefits from back home on Christmas eve. I had a fantastic time but after it all happened, I reflected and just thought how much I have missed "Julia". After continuing to look at my snapchat best friends, I finally just said fuck it. I gave all of my passwords and accounts to a friend and told her to change my passwords. 

After about 6 days, when I applied to colleges and everything, I went to a New Year's Eve party with my closest friends. I got hammered and all I remember the theme of the night was trying to get this girl off of my mind. And at that point, I hadn't really thought about her at all. I was enjoying my life and enjoying friends and doing things that make me happy. 

So now when I got back to my school, boarding school, I talked to my friends and we discussed breaks and everything and then we talked about Julia. I was venting and saying how I wish I didn't know her and everything when my friend said something that I'll never forget. 

"Oh you know that gift you gave her last year? Yea she threw it away in the trash."

After hearing that, I snapped I was so mad. I wasn't even upset, well, maybe a little, but I was pissed that she said that we will be fine and that she still cares about me and may be even friends a few years down the road. But now, I'm just straight up pissed. 

Am I correct to be feeling this way? I just feel betrayed and I guess that having her talk to another guy a week after we stopped dating? I don't know what to think anymore, and she is in one of my classes. What should I do?
<bot>: Girlfriend threw my gift to her away after we broke up and telling me that she still cared about me… What do I do? How do I go on about this?
