ChrisC99, kudos to you for following your dreams. I've been fortunate to live in Europe for 17+ years in five countries - including Spain. One regret I've had is that I was not able to provide my kids the opportunity to study overseas. Now, I work with many parents who are doing so, and there's no doubt, it's an incredible and memorable experience. Good luck in your endeavor.
I might have a few insights to share. My son is gay and has lived with us in The Netherlands and Italy. My nephew is transgender. His grandparents are Bolivian and his ancestors are Spanish. As a result, they both are well-traveled in Europe. Because of my work today and previously in corporate American, I've attended many LGBTQ+ conferences, including the initial PROUD conference in London a couple of years ago,.
As a "protective parent" you're always sensitive to any form of discrimination or bias toward your child. Thus, when we travel, how my son would be impacted is a "forefront" issue for my wife and me. Living in the Bible belt when our son came out, he had some tough experiences-. Frankly, living overseas, he has had far fewer negative experiences. In Spain, I am not aware that either young man felt uncomfortable in their travels. (Not to say it didn't happen, but not in an overt fashion). In my overseas experiences, Europeans - as a whole - tend to be more open on social issues and conservative on fiscal concerns. In the larger cities of Spain, Madrid, Barcelona, Valencia, etc., you'll find cosmopolitan surroundings and perspectives. In smaller and more rural areas, it's more conservative as folks tend to be older and less transient. I lived in Madrid and in the Basque region, and yes, we found northern Spain more conservative. But again, those are generalities, so seek your own answers,
This is a travel forum and living overseas is FAR DIFFERENT than traveling overseas. You'll see many overseas posters on the RS site, and you might reach out to them via a PM. I'd also suggest - as mentioned above - that you seek out other online venues. I've joined many ex-pat sites that assisted before and after I relocated to a new country. Facebook has many and I am sure you'll find others - even students studying abroad. Your fluency in Spanish will be a wonderful asset as I moved without being able to speak Spanish, Italian, Danish, German, or Dutch. That is a huge advantage, (my Danish friends probably spoke better English than I did!).
My first move with my wife was to Rome... and we could write a book on all the mistakes we made. But that was pre-internet and it's so much easier to research relocations these days. We've moved three times in the last six years and we researched incessantly. And our moves have gotten easier and easier (Of course, we're pretty experienced with 30+ moves in our marriage). Our next move will probably be to Spain, Portugal, Italy (my choices) or back to the USA (my wife's alternative), and we'll do our research.
I like living in Europe, love the opportunity to travel (well, except lately), the cafe lifestyle, and the less-hectic pace. Sometimes you tire of constantly having to "figure things out" and the bureaucracy can be intimidating (Italy, I'm thinking of you). We enjoy interacting with multiple cultures daily as our primary friends here are Dutch, British, Canadian, and Australian. You'll find strong ex-pat and student communities - and support - everywhere. And they'll be pleased to answer your questions. Good luck with your future plans.
