I agree that the amount of money you spend on your wedding is trivial. If income doesn't matter for either spouse or applicant, clearly this is a non-issue.
Sometimes couples recieve "red flags" when they are married without any family about. Untitled, you saidy ou had your mom, sister, two children and nephew so at least some family was there. What it comes down to is if you have a simple courthouse wedding it doesn't mean automatic refusal. If you have a huge wedding with 200 people it doesn't mean automatic acceptance.
Like everything else within the application, it's about how well you present it and all of the proofs combined. If the wedding is without any family members, perhaps include evidence where family members were about during the relationship/marriage. That will help ease the "red flag" scenerio.
Congrats on your husbands approval, untitled!
