Hi there, I'm enjoying the discussion here, and wanted to add my tuppence worth!
My view of unsecured debt is basically, if the worst thing possible happened, how well could you cope....
For me, your situation, would have me ask:
What if my partner gets ill, and new job doens't provide sick pay, how long could we survive, and if I had to go back to work could we afford it on the salary I would make?
If we broke up, how would we be able to fund 2 spearate residences... mortgage free now will probably not be mortgage free if you needed to set up 2 new homes. Would we both be eligible for mortgages (based on news stories of people being declined today who were ok-ed in the past).
For me personally, the level of unsecured debt you have would not leave me comfortable (i'm not a risk taker by any means).
Wedding wise, have the best day you can, but remember that money won't buy you the best day, your friends and family bring it! And limit the attendees to just the ones who matter, forget about dusting off Aunty Mary that only turns up at weddings, or people you work with that aren't your friends outside of the office.... its your friends and immediate close family that should get first dibs!
