You need to decide what's best for you. If she's with you all the time, and seems happy, perhaps it's a good idea to let the cell phone thing slide. I know in piecing it's best to avoid snooping (although I tend to do it!).
As far as the lack of physical intimacy, you should speak with her about marriage counseling, insist she go with you, and set up an appointment. I think that's your best bet to figure out what might be the problem in that area. Good luck to you!
There is no arriving, ever. It is all a continual becoming.
