It sounds like you are in a difficult situation. I can absolutely understand why you would want to work things out with your fiance. You obviously love him very much. Unfortunately there is only so much one person can do to make things work in a relationship. Not only do you have to be invested 100%, so does your fiance. I encourage you and your fiance to book an appointment with one of our therapists for couples therapy. Meeting with a therapist would definitely help shed some light on the issues that need to be addressed and what it will take to get where you want to be.
