Are money issues plaguing your friendships? Talk it out. For many friendships, this is no small task. "It's tricky to talk about sharing costs," says Jean Fitzpatrick, a psychotherapist and marriage counselor, "especially if there is a significant income disparity." "Don't be afraid to talk about it," she adds. "If you want to pay for a meal or event, be clear and say, 'My treat.' If you can't afford something, suggest a fun alternative." Money can be taboo, but having an open discussion can help.
