I am not able to understand the following use:

```

    ~がきにならなくなっていった
    
```

Does it mean I am/am not interested about the subject?  
Can someone explain the conjugation used here please?

Strange form of ki ni naru
> 「～～が気{き}にならなくなっていった」

≒

> 「～～が気に + ならない + なる + いく」

The last part いった is from いく（行く） and not from いる like you stated in your
comment above. I am sure you know both いく and くる are often used as subsidiary
verbs. (The past tense form of いる is いた, and not いった.)

「気にならない」 means " ** _to not be concerned_** ", " ** _to be free from_** ",
etc.

「なっていく」 means " ** _to (gradually) become_** ". It expresses a **_shift from
one state to the next_**.

Old state: Concerned

↓

New state: Unconcerned

Thus, 「～～が気にならなくなっていった」 means:

> "(Someone) became less and less concerned about ~~ (over time)"
