Complicated marriage

Last month I found out I was pregnant and a couple days later I had a miscarriage. My husband is over seas, and I told him about the news. Instead of talking to me about it, he talked to his ex fiancé. He had forgot to log out of his fb on my phone before he left. He lied to me about it until I screen shoted it and showed him. Ever since then I feel like I can't trust him. I really love him and want to make this work but it's so hard with me being in the u.s and him in Italy. Good news is I should be there by the beginning of May so we can at least try to make our marriage great again.
