I have a very simple solution to this and something that has helped my wife and I have a very successful and loving relationship.
The first thing you must do is spend as much time together as humanly possible. Right now if you don't do things together you need to start. For example, my wife and I do household cleaning together every weekend. We talk about everything during this time. We work as a team. At night we watch the same shows and we get ENGAGED with each other (I have a hub about this) and enjoy each others company.
The second thing is if you are having intimacy issues (which it kind of sounds like you were alluding to) then you have got to become closer. Start by scheduling your intimacy and being unique during this time. Figure out each others wants and needs then compromise.
You'll see I put a LOT of emphasis on communicating with each other - and this is critical if the not the most important component of a relationship.
