Is OTHER wrong in the post ? POST : Some time ago, my girlfriend of 1 year and me went out for dinner and drinks afterwards and had a wonderful time. While sitting there with our beers, she asked me to tell her something really beautiful, so i did exactly that, that i love her with all my heart and how i love having her etc. I can directly tell in her reaction that what i said didn't suffice her.. As we're of different nationalities and speak in her language, she asked me whether the expression "you're the love of my life" would exist in my language.

I told her yes it does and to be honest became a bit annoyed in my expression because i often have the feeling that i get tested whether i really love her. She then asks why i wouldn't tell her that, and i said "i don't know, i want to say it when i want to say it and not when i'm kind of forced to do it".

She: "but am i the love of my life"?

Me: "i don't know, i can't really say that right now, that's something so strong in my opinion, and that would be something i say when i or we want to marry and propose" (sorry for my english, don't know how to word it)

After that we went home in silence and she didn't want to sleep in the same bed. I was kind of lost and didn't really know what to do, i obviously felt bad for making her sad. 

The rest of the night is kind of like a blur, in short we tried to talk, she said that she always thought we would love each other the same amount and that she feels like there is a discrepancy in the way we love (and i get where she is coming from and i also feel so bad that i can't just tell her that she is the love of my life..). i then say that i don't really compare our love, that i know that i love her, and i want our love to get deeper and to fall into it with the flow, and that i feel like this flow gets interrupted by her kind of often asking me how much i love her.. she says that i broke her heart and humiliated her. i don't know whether i describe it understandably,  sorry for that, i don't want her to seem like the bad guy, i really feel and care for her, but i also kind of think i'm in the right?

AITA?
