For the record, I think that Italian is a beautiful language and that Italy is a beautiful country. I don't imagine that it is any more difficult to learn than Spanish. However, as others have already said, Spanish is both useful, widely-used, and beautiful.
When I was a child, I lived in Germany for several years. All the German that I learned I eventually forgot due to never using it. When I decided to try and finally learn a second language completely, I did not forget the lesson that I learned. Make sure that you are learning a language that you will continue to use regularly.
