Well I'm just trying to think of ideas as to why they would refuse you based on what you've said. So you two didn't have a honeymoon, which is fine, as long as you clearly explained it when you submitted the application?
Did you two live together after the wedding, and did you say that in the application? Was there a lot of pictures of you two and family members after the wedding ?
If you give me a run down on what you submitted on your app, how long you two have been together, if you two visited eachother at all during the sponsorship process I think we can figure out why they might of questioned the marriage. Just remember, you can always go back and either re do the wedding or go live together for a few months and then reapply.
