Can you ask Mr or Mrs X if I can borrow an itty bitty bit of money?

Back to your question. It's hard to answer not knowing what your current lifestyle is like.

I'd say if it was a problem for your husband other than him being a tightwad that might have some merit.

If you can truly afford it I'd say you stand firm on what you want.

Why look poor to your neighbors if you can afford it?
