Why can't I trust him?

Sounds suspicious to me. Let him go on his nudist beaches ALONE! Let him have his holidays alone. He doesn't want to love anything if he wants to destroy the baby growing in you! Leave him alone, I have a feeling he will end up alone his whole life. Oh, by the way when your child is born, let your lawyer get the child support from him. Take him to court, but let him be alone.
