What is the meaning 本心じゃない and ~言ってきた?


I'm unsure of what "本心じゃない" should represent and how to properly negate "本心"
in the sentences below.  
When I searched for the meaning of "本心", I found the following meaning:

-real intention  
-one's right mind  
-conformity to one's own sense of right conduct  
-really mean  
-true feelings 

Did the word "intention" properly conveyed the meaning of the sentences below?

> **本心じゃなくて** カップルイメ—ジに合わせちゃっただけなのに。  
>  It wasn’t intentional. But we still ended up becoming like a couples.  
>  私が **本心じゃない** ってわかっててあんなこと **言ってきた** んだ。  
>  When I understood that it was unintentional, I was saying such a thing.

I'm also unsure regarding how to interpret "~てきた". I tried searching for "てきた"
explanation and I found this.  
If the speaker at present says 「～てきた」, s/he is talking about something which
started sometime in the past and continued until now or it can be "until
sometime in the past".  
So, I interpreted "あんなこと言ってきたんだ" as "I was saying such a thing".  
But somehow the meaning of the whole sentence seems off.  
Is my interpretation of the meaning of "あんなこと言ってきたんだ" wrong or just the
interpretation of the sentence as a whole?




本心 means true feeling, as it says, and 本心じゃない means that what was said was not
sincere. So, 本心じゃなくてカップルイメ—ジに合わせちゃっただけなのに means "I wasn't serious, but just
obeyed to how she thought of us".

As for 言ってきた, when you express how someone speaks to someone else, if he
speaks to the direction that goes away from you in your perspective, you use
言う. In contrast, when he speaks to the direction that approaches to you, you
use 言ってくる. (note that these include psychological sense)

So, 私が本心じゃないってわかっててあんなこと言ってきたんだ means "Ah, so he told me that while knowing
that I wasn't serious!".

Without detailed explanations in the comments, I couldn't answer.
