This. This is why your marriage will be at risk. I trust my wife implicitly. I hope that she lives up to that trust. So far she has.
On the other side, I've not given my wife any reason to not trust me. Even when I was traveling weeks at a time, we'd talk every night and catch up on the day. If your husband is giving you reason's to not trust him, you have 3 options as I see it.
Approach him about it and tell him how you feel, then work out a solution.
See a therapist and deal with the trust issues you might be experiencing.
Ignore it all and live miserably until you end up separating.
I'd start with step 1...
