It seems as soon as we get a bit of money together something happens to rip a chunk out of our savings.
Situation one: you save for your wedding, emergency happens and you need to use part of your wedding savings to cover emergency so wedding postponed (again). But, emergency dealt with and life goes on.
Situation two: you take out loan for wedding, emergency happens - how do you pay for emergency? Can't save much because spare income is already spoken for in repaying the loan so you don't have an emergency fund (which, if you read money saving type website, you will know it is essential to have). Maybe you have to borrow money to deal with emergency, where from? Anyway, say you do manage to borrow it from somewhere. So, emergency dealt with and life goes on with you now having two separate amounts to pay back each month. And what happens the next time an emergency comes up?
I know you decided that you were just asking for advice on where to borrow money while unemployed but you really need to try to get out of this mindset. I was stuck in it for many years, and have ended up taking even longer to get out of debt than I should have because of it. It's also amazing how I would use credit to pay for some emergency and realise a year or two later that it really wasn't an emergency after all - your priorities do change when you accept your true financial situation. I'd suggest opening another credit union account and starting to save for your wedding there. Make it off limits for really anything but dire emergencies and see how far along you get. At the same time, even though it will take you longer to achieve your goals, save the same amount in your existing CU account to have as your emergency fund. Or save 1,000 for emergency fund, then start saving for wedding, for example.
By the way, you've said a couple of times that getting married in Ireland would be too much hassle (or something like that). You should start another thread on why that is - I bet you people here would be able to come up with lots of creative solutions. Like, if it's because of family, just go and get married in the registry office and then get some photos done with a Carribean background - still lots cheaper than going there. I suggest that only because I have a friend who did go to Jamaica to get married (to avoid the costs of a huge family wedding as well as avoiding the necessity of inviting hundreds of relatives she had no interest in seeing) and most of her photos, gorgeous though they were, were so idyllic that they really did look fake at first glance.
