Lehaa,
Cyber relationships are one thing... and even meeting in person.
You mentioned though that you are both from differing countries. That's where red flags went off, for me.
I see that you are in Australia. If... for example... the person you are cybering with, is in the States (U.S.A.), and you both are interested in each other, you will have a mountain to climb to be together Two mountains - if children are involved.
If you are thinking of coming to the states to be with him, you will need to get a special permission. If he is thinking of moving there - he will need a special 'skillset' that is in demand there - and he cannot be too old - to be desireable to Australia.
Basically, you will need to get married to this person.
There are all sorts of stories about folks who have done this - and succeeded... and also ones that have failed. (Long Distance Relationships are difficult.)
When kids are involved... it gets even worse. Australia will not let you take them out of the country - unless the other person - your ex - signs all sorts of papers. It can get messy at this point.
Lehaa, there are forums for Aussies - with this very situation - who post regularly - and you might do well to sign up with one or two of them. I used to belong to one of them... but that was so long ago... I do not even know how to point you to get you there.
I apologize if I sound so negative. I really wish you well... but I have been down that road - and learned a lot from that experience.
Good Luck... and I hope you don't put too many plans together before you investigate your options available to you.
Regards,
Jim TX
