<human>: Condense the text into a few key points

So, my 21st birthday is this Sunday. I was planning to spend it with him and have a really fun time, especially since my last birthday was not that great (spent it with my two friends and my ex, more of my friends were coming but my ex refused to drive after dark so I left before I saw any of them). We also live about 60 miles away through LA traffic, so visiting one another is an ordeal. 

However, I got mildly sick this week (itchy throat and cough, should clear up soon) and when I told him, he said he couldn't risk getting sick. I completely understand this, but he won't come over to see me or invite me over or anything. Since my friends all expected me to go out with him and it's finals, no one's free so I'm basically going to do homework alone for the day. I know it's whiny, but for some reason I'm just so sad and hurt. We've been dating for 5 months come Saturday, so it's not like I'm in a new relationship, but I cried a little which is disturbing for me. What's wrong with me and how can I make it stop?
<bot>: BF has a good reason to do something and it still upsets me- how do I let these things not get to me?
