@KateKate,
A few "weeks" of uninteresting dates? Meaning dates with a least a few different men over the course of mere weeks?
KateKate, while there a many people out there you may find yourself compatible with, you are shortchanging yourself in the extreme basing your inability to find Mr. Right in the matter of weeks.
This isn't sending a friend request to a near stranger on FB, or "liking" their comment.
I would advice practicing becoming more discerning in your tastes, and stepping back to see who may sooner (or later) meet you, and develop a mutually affectionate relationship.
Why so important it be "soon"? Have a good relationship with yourself first.
You can't force a square peg into a round hole. Even if you met someone on a date you found interesting, who's to say the feeling would be returned? This isn't a shopping expedition where you find something you like and bring it home with you. You're dealing with real live people who have their own personalities, needs and desires.
This man from the other country has expressed he is not interested enough to pursue a relationship beyond fun and some mutually good sex. There's nothing wrong with that. He's not using you, and thank goodness he's being honest.
If you want, continue to see him for the positive aspects of the relationship, and have some patience with finding someone of quality who is looking to travel down the same road with you, however long that may take.
