Can't think of one band where there was a couple and it ended up either themselves or the band breaking up.

Same here, in my experience. I also experienced a 'partner' who had nothing to do with the band I was in making suggestions and cajoling the female singer into a stance that conflicted withe the original idea of the band. What made matters worse in this instance was that he was the singer's 'bit on the side'. He was a known, feted guitarist up my way and had an ego the size of Jupiter. He worked his magic with the singer and even though he was told to keep his distance the band imploded not long after that, though he/she were not the main reason for this happening.
IF I ever got involved in a band again, I would not entertain working with a couple, nascent or otherwise.
