The paranoia lessens over time with consistent behavior on his part and a verbal understanding of how things should be. If he is still doing what he feels like when he feels like it, no, the paranoia will not go away. And really, you'd be foolish to let it. There has to be communication, and a desire on both of your parts to be committed to the marriage, and to make the other person feel loved. My advice is to talk about in a quiet, loving way.
