Boyfriend drama

So my boyfriend decided that he wants to go in to the national gard. He is leaving in the next three months. It makes me extremely sad because I am madly in love for the first time in my life. And now that we put had this talk I can't help but feel hurt. The more we hang out the more I fall in love with him. And it kills me to know when we are going to end. Sorry for the emotional rant but I just needed to get it out.
