So I did the test myself and the result was as he said. Here is the result of that test:
Your name: Carin
Name boyfriend: Luuk
Result:25-50% Mmmmm... It was or is maybe fun together, but your loveparty won't last long. You are much too different and both of you like complete different things. It is better to go and find someone else with a completely different name!
Of course this result is a little strange as we have been married for nearly 17 years and are still very happy with each other. So I did the test again with our real names which our son doesn't know as we never use these names. Well the result was definitely much better.
Your name: Anna
Name boyfriend: Lucas
50-75% There is a big chance that you will stay together! Your love is very strong and you have lots of fun together! It is still a question whether you are the right one for each other... Anyway you will have terrific fun for a very long time and one thing is sure: friends you will remain forever!!!
At least this test proves that we do match and so far we did stay together for a long time and are intending to stay together much longer!
