I am sorry you are hurting...if your bf feels that he is in danger (and it is not a regular part of his job) can he take a couple of days off? I am sure if he were concerned, he would call in. He is an adult, too, honey and he has to do what is right for him. No amount of worry, pleading or begging will prevent that. He has his own mind and knows what he can manage. Send positive thoughts and try to think of good things. Ask him if he could check in with you during the day just so you can touch base. Also, dont forget to tell him you love him. Everything will be ok.
