如果夫妇之间有人生病或不舒服，别人就照顾那个人两人能彼此照顾。

"别人" and "有人" aren't that specific. I think you wanted to express that couples (in general) can take of each other in case one of them falls ill?

当然有时间吵架 当然有时间 因为我们都要如何分负责只他们俩互相交流为啥”我生气“就好，夫妻之间有时候会吵架，这在分担责任的时候很正常。但只要双方能够沟通，彼此说明“我为什么生气”，很多问题就能解决了。

Your speech marks were off, but that could just be a typo. Don't forget commas as well. '我们都要如何分负责' is incorrect, translating to 'We all need to how to split take responsibility for each other'. 如何 is a way of saying 'how to do so and so', so using it would be wrong in that context. I think by '分负责', you meant splitting responsibilities, but it isn't grammatically correct, '分担责任' is more accurate.

另一件重要的事情是：完美的关系是 60/40 俩都试成一百之六十，因为 50/50 是不可以的 有时间丈夫有问题 有时间妻子有问题 所以最重要的是你故意偶尔是60于是别的也做这样并不是50/50的平均分担，而是60/60。也就是说，两个人都尽力去做到60%。生活中总会有夫妇当中某人遇到问题的时候，所以俩人应该愿意多承担一点。
