Ok, IME there is a huge difference between crying in the phone saying they want to be a great parent and starting to make arrangements to be one and carry it through for as long as the kid needs it.
It is a short holiday romance and the fact that you are in different countries makes it almost impossible to sort something so he could see his child grow.
I am divorced but have been raising my child fully and absolutely single handedly in a country that is not my own (I couldn’t take my son back home and I don’t have he money or the energy to fight in court to allow us the freedom to leave, my son’s dad is totally out of the picture though but has a court order that prevents me from leaving).
If I were in your position, I would try to enjoy as much as possible this pregnancy, assuming that it is very unlikely he will stay in the picture for long. No need for dramas during your pregnancy, it is not good for the baby and you cannot do anything anyway.
With regards to parental responsibility. I find it to hear so many people always advising not to put him in the birth certificate as if with that you can keep the child to yourself. This is totally outdated advice. In these days of DNA testing, the only thing that you or atthe dad need to do is request a DNA test and If positive, they will get parental responsibility whether you like it or not, unless the dad presents a very clear and imminent potential that he might hurt the children.
Whatever you do, don’t take the child to visit dad in his own country, if he has a court process in place about the kid, you might not be allowed to leave with the.: kid.
