Imacdonald - I don't think anyone is being nasty or sarcastic - they are just enquiring as to WHAT you were wondering about as to what you think you could be entitled to!
You have rights to the house if you are co-owners, but you have no rights to his salary, and you have to try to come to an amicable agreement about share of posessions. Of course, solicitors can sort this legally but, boy this will be costly.
I sadly think you have nothing other than the share of equity ( or your responsibility of half of any negative equity ) and a hope that this can be sorted amicably.
Sorry if this isn't what you wanted to hear :-(
