Never ever date a foreigner unless you are sure that(in this order):
-he wants to stay a while
-he has applied for the long-term visa(he won´t have to leave after 3 months and stay out of the country and the EU for the next 3 months)
-he is worth the increased risk of you getting hurt (and the ugly comments you get from people you meet)
Skipping steps number two and three is not worth it.

She's lonely
And he says
It's for her only
That he lusts
She doesn't trust him
Nothing is true
But he will do
