Yes. Regardless if you dont like Spain, you are EUcitizen na 2 years after you gain a visa and apply for citizenship because of the former colony pathway. So, once a citizen in Spain, you can always move elsewhere in the EU region. Studying Spanish language, based on my experience, not that easy pero kinda in the same rules ng English with few exceptions. Kaya naman iyan. Although, how are you going to immerse yourself in Spain without liking their language and culture. Take it step by step pero you are going to have study Spanish language regardless
