I need advice on this one?

Ok so my boyfriend of 6 months has been going through a lot lately, especially on the emotional front. Plus he is going away for a while to a dangerous place, and I know it's really weighing on him. About 3 weeks ago, he stopped saying "I love you" to me, now if I tell him I love him he will tell me that he loves me too. And his actions show that he does care still. I just don't know if he really loves me, and I don't want to put more stress on him by berating him with do you love me questions especially since he is leaving very very soon. I really need some advice
