I am writing a blog. What language to use?
Well…my native language is "Chavacano", it’s like a broken Spanish. haha. Then my 2nd language is Tagalog (My country’s National Language). Then English. So the problem is, I don’t know what language to use. :[ Help please. 
By the way, my blog is about the happenings in my life and some tutorials.
If you want everyone on the Internet to be able to read it, then definitely English. However, using native language makes readers a bit more familiar.
Personally I think you should use either Chavacano or Tagalog for the parts about "happenings in my life" and English for "tutorials". And if feasible, they should be on a separate blog site/account (so not to confuse readers that can only read one of the language due to a "nonsensical weird text").
