I lived and studied in Europe for 5 years, and I loved it and it changed me forever. I studied in Germany, but France, Northern Italy down to Rome, Belgium, The Netherlands, Switzerland, Spain, All these would be wonderful. I never wanted to go to Great Britain, because I didn't want to speak English. But I did spend 3 months there while working on my doctoral dissertation, and it was wonderful too. (I forgot that English is your second language. But if I were you and her and it could not be UK or in English, I'd choose French or Spanish as my 3rd language, because they are more widely used than German, which is my 2nd language, with French 3rd, Italian 4th, Greek 5th--but each one less proficient than the one before it. I'm confident that with 2 months of immersion language school, which I'm sure they have in France, Belgium, Italy and Spain, you could get good enough at any one of those 3 languages to take classes. And I bet that the Netherlands has some college level programs in English, and Switzerland might also.
I can help with your girlfriend's problem. I got Herpes from a brief girlfriend in 1976 and had an accident that gave it to my wife in 1989. She still gets brief outbreaks when she has high stress, but I almost never do. It is much worse for her than for me because of our gender differences in anatomy. There is at present nothing that will kill it off for good. BUT there is a very cheap chemical available in capsules online that kills is as well as the expensive medical (patented) drugs: It's called BHT, or Butylated Hydroxytoluene. A friend from the late 1970s who had been a pharmacist in the American army in the 50s told me they used it for herpes in the military.
BHT is a cooking oil preservative. It breaks down the fatty membrane that protects the herpes virus, and that allows your own body to kill it in 2-4 days. That's actually BETTER than any newer drug, because your own body gets better at killing the virus, because all BHT does is dissolve its main protection. BHT is also mentioned in some books on "Life Extension" because it kills free radicals in the body, and those are major agents for aging and breakdown of body defenses against things like cancer. (The big drug companies won't research BHT, because they'd just lose more profits from their patented drugs.)
There are two possible down-sides to BHT: 1. since it dissolves fatty membranes, it can weaken your stomach walls, and if you have a sensitive stomach like my wife does, it might make some high acid or spicy foods hurt your stomach walls. But you don't take BHT except during an outbreak, and you could take an anti-acid from a drug store during those days. I might take 3-4 pills the first day, 2 the second and 2 the 3rd, and it'll be healing over. But women won't be able to see it healing, just feel it.
2. BHT speeds the metabolism of alcohol in your liver, so you get drunk faster and get over drinking faster. I used to drink too much once in a few months in my mid 30s after I got herpes, but rarely ever since then. Obviously alcohol should not be drunk during an outbreak. But for dealing when drinking, it's best to take the BHT when going to bed after drinking, so the alcohol is all metabolized by morning and there's no hangover. (But the most important treatment for hangovers is to drink plenty of water while drinking alcohol, because most of the headache is due to dehydration.)
I assume you can get BHT shipped from USA (at least) in 250 or 500 capsule bottles. At 6-10 caps per outbreak, that's a lot of treatment capability. I've not kept up with any newer treatments, because I don't need more than 1-2 days worth anymore and my wife refuses to take it and doesn't want to figure out how to protect her stomach so she can take it: She also rarely has outbreaks anymore. A man I knew who had it himself told me that in dies down after 10 to 12 years. I've found that to be slower for myself, but it was pretty infrequent for me by 1989. (In fact I didn't know I had it, because I had just arrived by flying back from Europe, and I didn't know that flying at high altitudes can cause an outbreak--so keep that in mind when you travel.)
I have to go now. I hope that helps.
