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 fiancĂ©. 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.
