I think I speak for everyone that has ever been married, divorced, or closed the chapter after a long term relationship, the dating world as an adult is possibly one of the most scariest experiences in my life! It's much deeper than, "What's your favorite color"? We've to match goals, dreams, lifestyles, aspirations, etc. up and figure out the kids talk. Not to mention, when is the appropriate time to introduce the children, if they have them and vice versa.
Dating when kids are involved can be a challenge on its own. Setting those dates while working around the other parent's schedule can be tough. Phone dates can be just as fulfilling but nothing beats sitting across a table or feeling them beside you as you each share experiences and find common ground.
