세 번째 단락 네 번째 문장이네요.

He hung out in your womb for a few month back in the 80s. Since then, I have grown to love him just as much as you!

그는 당신의 자궁 속에서 몇 달간 있었고... "back in the 80s"-->(어떻게 해석하죠?),

I have grown to love him just as much as you! --> 나는 그를 당신만큼 사랑한다.라고 해석하면 될것 같은데 왜 have grown to love라고 썼나요? 의미의 차이가 있나요?
