<human>: Can you provide a brief overview of the text?

So we've been seeing each other for two and a half months and have made it clear that were dating exclusively but are not in a committed relationship because we leave for different colleges in a week. Yesterday we talked about how in social settings she feels like an "accessory" when she's with me because people see her as being with me and not us being together. 
I told her that I understand where she's coming from and that we can keep any intimate contact to when it's just us/her close friends around, and in group settings we can just act like friends. 
So today she was at work and told me she was tired so I surprised her with some coffee. Now usually when she's working with her close friend I'll get a hug and a kiss when I show up to where she works, but today she was working with another guy my age (and no before anyone says anything I know she isn't cheating) and I got a smile and a Hello/thank you from her but no hug or anything. 
I know she diddnt do anything wrong and I know I was the one who brought up the idea of acting like friends in certain situations but it was just one guy who neither of us really knows very well and it made me feel somewhat hurt to not get a hug or anything, so my question is how do I let go of these feelings for the sake of enjoying the time we have left together?
<bot>: SO and I agreed to act like friends in group/social settings but I still feel hurt by it, how do I let go of that feeling for both our sakes?
