Edit. Ok, to tell the truth, I don't feel very compelled to maintain a good spoken Italian. On the other hand, I do want to keep my written version as sharp as possible.
I'm Italian, lived in UK for a few years, and I have problems with Standard Italian, so much that often I use English grammar in Italian or I have to Google translate from English to Italian for words.
Also, I noticed as well that my home dialect is getting stronger than Standard Italian, although I lived in another part of Italy for almost 10 years.
P.S. You may find it useful that "since 8 years" is awkward in English, "for 8 years" would be preferred.
Seriously, once you look for it, you see it very clearly. You can usually spot Italians writing in English for their overuse of "the", their sentence length, and a higher frequency of passive verbs. If it feels like that but the number of "the"s is correct, the only explanation is that you are reading Ian McEwan.
Also, I didn't notice anything off while reading the post.
It could definitely be influence from the Italian language.
