<human>: Give me a shortened version of the text

Hi reddit. My boyfriend (Tim) and I go to college together, I am and junior, and he is a senior who will be graduating in May. He will be moving away for his job, thus we have decided to break up- we both know it's for the best. Neither of us want to do long distance (we tried it before when I studied abroad in the fall) as we do not plan on being in the same place after college, and neither of us were willing to sacrifice our future goals for our relationship.

That decision was hard but I know it's right. The problem now is that we decided to stay together until he graduates and I don't know if the way I'm dealing with it is unfair to him. I often catch myself thinking about and behaving around other guys as if I'm single, knowing that I will be soon. When I say behaving around, I don't mean cheating, but sometimes I'm more flirtatious. People have asked me a couple of times if I'm single because of the way I act. These "other guys" are my friends who know what my situation is.

Should I feel guilty about this? 
Am I wronging Tim? 
Am I leading on these other guys, even though they know I have a boyfriend? 
Part of me feels like it's almost more healthy to start detaching myself from the relationship and letting it die naturally than trying to fuel it until he's gone and then just have it be a huge shock when he leaves. Should I maybe break up with him sooner? 

I think I'm ready to be single, but he's leaving soon and I think it'd be nice to spend these last couple of months together. He's my best friend and I don't want to hurt him or cut things off early and go no contact, as I'd like to stay in touch when he leaves.
<bot>: My boyfriend is graduating and moving away, I dont know if the way I'm handling our impending breakup is unfair to him, or me, or other guys.
