Does This Fear Ever Go Away?

Its kinda like AA...my name is Kim and I am a firemans girlfriend! At first I was just so proud that this selfless (sexy) man was interested in me. But as our friendship turned into more, I started to worry. Im sure most of your boyfriends are the same, they LOVE fires. Mine lives for them. Sometimes he texts me from the truck on a call to tell me what kind of call it is... rescue, gas leak, etc. He texted me one evening with one word that changed my life forever; fire. I immediately experienced a feeling that I didn't even know existed. It was a combonation of excitement for him because I knew he was giddy, but for me total and utter fear. I panicked... I was so scared of something happening to him. Now its all I think about. We've been talking recently about a future together. But I need to know- does this feeling ever go away? Or at least get better over time? I love him so much and I will stand by him through thick and thin, but will I always worry like this??
Thanks for reading.
