My partner's OW is two years older than him, has four children from two marriages (going through divorce from her current husband) and has three grandchildren.
They are trying to relive the carefree days of their time at art school together thirty years ago. If it was all so marvellous then, why didn't they stay together? Strangely, neither of them can apparently remember why they broke up then.
I think she is probably going through some sort of MLC as well and isn't a golddigger as my partner earns a lot less than her husband. She has no income of her own so he (my partner) is paying for everything. When he came back for a week, he did tell me that she was very good at spending money and I suspect her lack of income will make it even more difficult for him to leave her as he will be worried that she will be left with nothing. My heart bleeds....
