As you can see quite well on the pictures of Prof. Busselen, the petals of Stellaria media are almost completely divided, whereas those of Cerastium fontanum vulgare are only 'cut in half'. The leaves of the first one have a more 'succulent' aspect (don't know if that's the correct word in English), and don't have the hairy aspect that has the second. I see know that the latter is called 'Common Mouse-ear' in English... that's of course because of those hairs on the leaves....
