No not just you. I would his behaviour quite strange too, why Dutch women is my first question? Sounds to me as though he is just using you to fill his time once a week!
Come on dear your worth so much better. Don't undervalue yourself.
As for dating when your older yes it's a minefield, yes it's scary and yes you should be wary.
None of the usual dating websites do any background checks and that in itself tells you how easy a target you are for the most unsavoury characters, be careful, don't give too much personal information if you take that route.
People usually say join a club an interest you enjoy like painting, sports, music and so on, however if you're anything like me I am not a joiner which makes meeting anyone taking that route a big no.
Your still young I know that sounds totally inadequate and blaze but I hope you meet someone in time you'll find happiness and fun with.
