Is she a gold digger,a male relative of mine,,,i think someones trying to rip him off?

he is 52 she is 54, he has his own house no mortgage,she has 2 grown up children and one at school,after 6 weeks after she started seing him,she asked to borrow money about two hundred pound for her car.a few weeks later she asked to borrow eight hundred pound said she was in bad debt,all in all he gave her six hundred pound,he finished it before last xmas as she asked for a computer,,he thought she were teking the mick,, the last two months she has been crawling round him,she has asked to borrow money he said no,but she still hanging round him,helping him with the decorating going shopping ,,,she isnt even using her right forname either for her age its completely out of date,she tells him lies ,,,meets up with people of the internet,and tries to get him jealous by saying about all the attention she gets and admiring looks of men,,and hoe they want to take her out ,,,,why cant he see what she is like,,is my relative to be wary or what any one put my mind at rest cheers emma xxxx
