She ignores me but I devote every second to her...

[Acsacal]

She ignores me but I devote every second to her; She lies to me but I always tell her the truth; She calls me weak but I would fight through anything for her.

Kinda long but I hope someone can translate it. Many thanks in advanced for this.

To discuss. This is not a translation ad verbum, but a similar idea.
