Why is deployed husband treating me badly?

Everything was fine before he left. He just arrived in Iraq and i missed his phone call twice in a row. He left a voicemail using swear-words that i need to leave my ****ing phone with me if not hes not going to *ucken call. He got mad at me again for going out with HIS friends, and tole me he doesnt really trust me, even though i havent done anything wrong to make him think im not worth trusting. Idk why hes saying these sort of things to me... what should i do to handle the situation?
