The best person to talk about the problems in your relationship is the person you're in a relationship with.
The relationship, whatever form it may take now and in the future, is already in motion. It is already bringing up the right issues. Regardless of its destined outcome, it is working in that good/bad, pleasure/painful way that important relationships do. Keep your own eyes on a straight course of love and trust and it will help to move everything in that direction.
