don't look too much into it. just tell him something like, "as long as you're being faithful to me i'll be faithful to you" or if he asks if you've been cheating tell him that you're only doing what he's doing. if a shitstorm starts instead of him shutting up you know something is up.

That's what I've told him multiple times... He's never cheated(or at least haven't gotten caught) but something inside me keeps telling me something isn't right @l0tus

does he have a history of cheating? my ex did the same thing and constantly accused me when i said our relationship needed work. then i found out he had been messing around with other girls and it was just the guilt eating at him
