MyMe, Myself and I [all major words in a title are capitalized]

Hello. My name is Alejandro, and I am 22 years old. I'm from the north of Spain,  a region [or town] called Asturias. I really like to listen to [or listening to] music, the Eurovision Song Contest, cinema watching movies, and learning languages.* I study Social Integration to help people who are in social exclusion marginalized and excluded from society because the of drugs, use, inmmigration, bullyng, or other issues... I would like to work helping all these people.

I live in Oviedo with my boyfriend Miguel. He is from Córdoba, on in the south of southern Spain, but now we live together in Oviedo. He studies Spanish at the Uuniversity** and works like particular as a special education teacher with children with special needs.*** He really loves his work. We started our relationship at 25th December 25, on 2012 [or Christmas Day, 2012]. I love him so much,; he is my prince.

We live in a flat with one girl from France, two girls from China and one girl from Mallorca. We only have a good relationship with Andrea, the girl from Mallorca, because the others are very strange.

* this is just a stylistic suggestion; there is greater parallel construction when all verbs are in the same tense: listening, watching, learning

** shouldn't be capitalized unless you use the actual name of the university

*** I'm just guessing at what you meant by "particular".  If he works with children with physical, emotional, or behavioral disabilities, we now refer to them as "special needs children" or "children with special needs"'.  Their education classrooms or programs are referred to as "special education" or more informally as "special ed".  If I misunderstood your meaning, just forget what I said.  :- ) 

Nice writing!
