Love /
Polish Girlfriend gone missing [154]
Shit mate, that's a horrible situation to be in. I don't know what words or advice I could offer other than the steps you are already taking.
Basically if you love her then I would go to her hometown, if for nothing more than to get some sort of closure. How big is the town? You might want to bring a picture and ask around the town centre if anyone knows her. If you know what classes she is taking at University then I would go there and ask her professors about anything strange like her suddenly dropping out.
I wouldn't give up on this, it seems like outside forces working against you two. Sadly those outside forces were too much for my ex it seemed but it doesn't sound like she wants them to if it wasn't for the sake of the hospital visit.
Definately go to the hometown. Maybe go to one of the language schools in Krakow and explain your story and ask if anyone would be willing to travel with you and help translate. I realise that's a big ask, but I have found a lot of the students to be extremely nice and I'm sure, after hearing the story there will be someone happy to help. If it's a small town they probably won't speak much english so it will be handy to have a Polish speaker with you.
Best of luck mate, let us know how it goes.
