Marriage and faith

Hi everyone, I’ve been married for a year I’m 29 M my wife 30. We met and fell in love even though we knew I was not a big believer. She prayed for it and now we’re married. Our weeding will be July next year. But I don’t feel anything about Christianity, now she wants a Christian wedding and my family is not Christian and all of them are saying it will be boring. I don’t event want to invite close friends cause they’re not believers as well. I just want some advice because I don’t want a divorce. How can I feel God? I’m agnostic so it is really hard for me to feel something. I just go to church and help in whatever I can because of my wife but I just feel hopeless and faithless . What can I do in order to feel that God is with me and not feeling ashamed of my wedding, faith, religion, etc? How can I believe?
