Where can a 55 year old woman find a new partner?

A friend of mine, who is like a mom to me, is coming to the end of her 25 year marriage. They're "waiting" until their son goes off to college to make the final split, driving each other completely crazy in the meanwhile. She and her husband haven't had a nice relationship for a long time and I feel there must be men out there who are in a similar state of relationship limbo. They are both admittedly done with their relationship, but due to financial reasons they feel compelled to stick it out. I think it'd be great if she met someone who would really see her as the funny, spunky person she is. Anyone out there with a nice, single, divorced/widowed dad out there? :-) I think it's harder for the older generation to see the possibility of meeting new people--especially new people that you might like to spend the next part of your life with. Any ideas of what I should recommend for her?
