Indeed, it is upsetting that your family do not want to be involved with wedding plans. However, I think that once your family realize how happy and settled you are with this man, with the stable life he can provide and the loving encouragement he gives you to fulfill your dreams, they will realize that your love surpasses religion and culture.
You must focus on your long term future. Continue to encourage your family to join you in your wedding plans but be calm and composed when they decline to do so. This will demonstrate your maturity which they will no doubt respect you for in time.

Best wishes.
