Even my mother

Even my mother, who I was closer to than anyone else on the planet, was never in harmony with me, never on exactly the same page.
closer是表语？
to than如何理解？

be close to sb, 和某人关系近,于是，改成比较级就是，be closer to sb than sb. 比起某人，和某人关系更近，然后定语从句，变成了，who I was closer to than anyone else on the planet.那个我在世界上最亲近的人。

closer 是表语。

be close to 表示比别人更亲密，固定短语，不是to than ，to 是接在close后面的，than是比的意思

我母亲甚至比上帝都伟大。
