What can I do about this situation?

Hi I am a Chilean girl and I have an English boyfriend (Anglo-Saxon ). Well I am a pretty white latina and I am a very nice person, but the problem is that I never thought to have an English boyfriend who works in the birtish army. Now I am very worried about him, because he can die..now he diployed in Germany :( ...I havent told my family that my boyfriend in is the British army, my familiy is ultra conservative like all Chilean families and if they know that he is in the army, they will kill me hahaha..but I am very worried about my boyfriend because he can die =( , he is a very nice man ..What is your opinion about it?
