Perhaps you could ask him to attend one of your sessions with you? Make it seem like you want him to come for you, not because you want him in therapy. Maybe once he sees what goes on behind the closed door of a therapy session and working with you on the problems you're experiencing in your life, he'll be more open to the idea of going to couples counseling to help the both of you work together.

Have you talked to your therapist about this at all? What do they say? Perhaps you can have practice conversations with your T before talking to your husband.

I'd also be extremely upset if my fiance hid his facebook friends from me. In fact, I'd be down right angry. But I don't know how I would handle it or what I would do or say about it, either..

Also, maybe you should remind your husband that work cell phones are for WORK use. He could get into serious trouble using his work cell phone for non-work related activities. They gave it to him to use as a tool for his job, not to play around on facebook.
