What other people think is irrelevant. If you have hang ups about it then it's not right for you. For others it is. Many people are not that fussed by an age gap and for others it is just an ego boost.

You do not have to be mentally or emotionally unstable to date someone younger than yourself. If you have such concerns having met her then talk to her, if you can't do that then you have answered your own question.

Mutual Match is a complete waste of time for anyone who lives near a major river with few crossings.

Living in Kent, Mutual Match shows me everyone from Essex and hardly anyone from Kent? It's 30 to 40 minutes just to get to the bridge and get through assuming there are no hold ups, which coming back there usually are. I don't want to have to wade through them, I want to see people from Kent. Is that to much to ask?

Presumably this site is based on milage as the crow flies, Basildon and Southend being relatively near but over an hour away by car, as there seems to be no county field.
