Understand one thing: Your problem is not going to go away by itself. It exists and MUST be dealt with.
In a non-confrontational way, you must take the initiative and deal with it, whether its as simple as getting a bottle of wine and sitting down and talking about you two as an "us" or taking a walk somewhere to neutral ground.
People are selfish, but do not see themselves as selfish.
BTW, if you do not deal with this now, I promise, it will get worse and you might (unfortunately) learn how to deal it by lowering your standards of behavior that you expect from a loved one.
