I Need Advice

I'm engaged to the man of my dreams. I love him more than anyone on this Earth. He loves me the same. The advice I need is how to overcome the people who aren't happy and/or jealous. I was raised in a religion where marriage is of the utmost importance, but was willing to wait for the right guy to come along. I have another friend who is getting married around the same time as me. She was engaged first and wants me to move my date back 4 months so I can attend her wedding. Another friend is angry that I didn't follow her exact instructions with my relationship (which apparently were supposed to lead to the relationship ending). Another wants me to tell her about my relationship with God and how that is playing into this decision (something that is personal and sacred). I am going crazy because of the jealousy (I don't get jealous of other people's relationships for a few reasons.) I just don't know how to make amends when they want me to apologize for wanting to get married and finding the man of my dreams and being happy. Feel free to ask questions about the situation. But how would anyone else handle this without cussing anybody out to their face?
