Think you need to have serious chat with your fiancee as you're so clearly not happy with her doing a job in which she doesn't get every weekend off! Possibly sort this before the wedding!
I actually think that the fact that Virgin allocate leave in seniority order is great seeing as seniority counted for bugger all else now and V swap is definitely the best and most helpful thing the company have ever done for us. There are a lot of things that Virgin do that really p*ss me off (don't even get me started on CSMs!!) but V swap is great, to be able to completely change your roster is something that not many other companies would allow.
You can get unpaid leave for weddings-your fiancee would need to speak directly to crew records (address on IFLY). No point speaking to CSMs as they know nothing!
Just out of curousity, does your girlfriend feel as annoyed by Virgin as you do?
Don't mean to be nasty-just you seem very negative about a lot.
