Help me. I trust my boyfriend 100% when he's here at home with me or in the same town. I know he wouldn't ever flirt or cheat on me. But he went out of state for a week to work with his brother. I'm scared he will cheat on me and I won't ever know. I don't know why I can't trust him when he's away. I love him so much. I know he wouldn't do that but there's something in my mind that tells me he will.
