The real intimacy begins with trust. If the two of you can not be sincere and suspect each other in all possible sins, the feeling of internal loneliness is inevitable. The elimination of psychological distance is a cooperative process which requires some efforts from both of you.
The first rule of es6tablishing trust is to speak openly about your feelings. It concerns not only love and admiration, but also your reaction on some of his actions you do not like. Be calm and confident, speak without hysteria and accusations. Of course, there should be a mystery in woman, but it is better to hide this mystery not in the sphere of feelings.
