What should I do about my dad and ex step mum?

I wil start at the beginning, so here goes, my dad and step mum, well now ex step mum are in the middle of a divorce, my dad stayed in the bungalow where they both signed an agreement to pay their half of the rent and she moved back to her home town which is newcastle. When my dad an rita (ex step mum) split up, she left straight away with nobody knowing where she went to, I still talk to her but im in a bit of a predicament now. My dad is in loads of debt because of her moving and not paying any of the bills, my dad is now classed as disabled as he has realy bad problems with his back and legs. He is waiting for an operation on his shoulder also, so he is on the sick! The people that own the bungalow want there money like now and my dad hasnt got it. Now I have ritas home addres were she is living, and her phone number but if my dad finds out he will fall out with me for having them and still talking to rita, my dad could end up in prison because of all this debt, and hes about to get kicked out of his bungalow and has no where else to go! What do I do? =(

        A- give my dad her address and have the risk of him faling out with me as well as rita as she made me swear down I wouldnt give it to anybody!

 B- leave it alone and my dad could end up in prison/on the streets, or even killing himself (as he keeps telling me thats what he feels like doing)

So some advice would help rite now!! As once again im stuck in the middle of them both weather they know it or not!! Thanks in advance
