That's the problem with only studying one language, you're always thinking about the other ones you could be studying instead. At least that was my problem before finding HTLAL, I couldn't decide between Arabic and Croatian so I learned neither. Have you considered learning both Spanish and German? Or you could focus on studying German while using the Spanish you already have in your community or for consumming media. You said there are no movies you want to watch in Spanish, how about asking for recommendations? What about music? Books?
I fall in love with the languages I'm learning by becoming friends with people who are more comfortable speaking that language than English and by actively seeking out media to complete the Super Challenge. Other than reading the Master and Margarita in its original Russian (a language that I'm not starting anytime soon) there's no book, movie, or tv show that I'm dying to see in any language other than English.
If languages are like relationships then I'm definitely a polygamist. Serial monogamy might work too, but I probably couldn't stick to just one language for more than six months before moving on to the next one.
So my advice is try studying other languages at the same time, if you still hate Spanish while being free to study all the other languages you want, then it just wasn't meant to be.
