sweetnote143,

Maintaining a good long distance relationship (LDR) isn't easy. A lot of couples even suggest that they have more quarrels in LDR than when they are together in SDR (Short Distance Relationship)

Based on what you've already shared with us we know that you haven't physically met so far, and that this LDR has been 6 months in the making.

Maybe I'm way off base here, but I feel there's already been plenty of quarrels, and, in my view, mostly about who has control.

In any LDR putting your trust in the continuance of communication, through thick and thin, is a key issue. All relationships can be a risky business for us and we all risk getting hurt from time to time. Quality relationships also need effort. An effort that shows just how willing are we to go out on a limb and sacrifice a little vulnerability for the greater good?

It is fairly well publicised, even in this forum, that requests for money under any circumstances is an almost surefired way to bring the word 'scammer' to mind and to tempt the end of communications.
I hope you can really understand and accept that possibility.

On the other side of the coin I have some harsh words.
It could also be that in this LDR your B/F is abusing you. In this LDR your B/F is abandoning you. And he's not even giving you a chance.

Silence is a cheap and easy way to control and direct one of the most hurtful and abusive things to do in my book.
It's a horrible feeling to be ignored and be denied affection. And there's nothing you can do.

Whatever his reasons my personal suggestion would be to try this:-
Firstly, apologise that you may have said or done something to upset him.
Honestly express just how his silence makes you feel. That you want to work things through by talking, but his behaviour prevents that.
Explain that his silence is impacting your life and wellbeing, and that if it continues much longer you'll assume that he no longer wants the friendship and you will not wait any longer.

It has nothing to do with traits of either foreign men or men in general, but maybe more to do with the traits of insecure and control seeking humans.
No offence intended.
