LOL topogigo, firstly, you are never too old!
And as for being 48, you are just a pup, mr warpig is 46 and soon to be a father for the first time!
The only problem I can see is the financial arrangment of the rent. If you enter into a relationship with her and say for example she cant pay the rent for a month then what do you do? There is the old addage of business and pleasure dont work. That said, mrwarpig was my landlord when I first met him umpteen years ago.
