I'm deeply sorry for my poor english skills but I need to know. :(
Can I answer: "It always has been happening" after the sentence: "This is happening because of you" ?
Adverbs of frequency (always) are rarely used in the continuous tense. It is preferred to use simple tenses instead. So, instead of Present Perfect Continuous, I would choose Present Perfect Simple. But since "It has always happened" would not address what you mean, the fact that something has always been the trend, I would choose Present Simple. So your answer would be It always happens.
