Hi lost_in_us,
wow, not a goood senerio.
Not easy for you to get a handle om whats going on when you don't rally know how she feels, even though all the signs are there saying you have been used as a means to an end.
The thought that this for her may have been a holiday romance that she never thought would follow her home.
I think you really need to think hard about where you want to live and make that your first priority, if you don't like the old U.S of A and prefer to live in the lucky country then come home.
Do you have employment over there or are you relying on others ?
Are you sure the child is yours ?
Are you staying in hope that you can rekindle the romance you has ?
Sort your feeling out and be sure it's what you want, there are many variables that you must take into account before you can committ to being a Father.
For instance how will feel if she refuses contact and what will you do ?
How do you feel if she starts a relationship with someone else whilst she is pregnant ?
How will you deal with it ?
Good luck I really hope you keep posting, your a long way away in a foreign land and that in itself is emensly difficult.
Best wishes
