这句英文我怎样说行吗？

加个to, I have no more time to spend on you

I don't have much time on you. 最简洁。

你的句子要改成 I have no more time to spend on you.

i have no more time spend on you
这句话语法有点小错误，如果在time 后加to,或者spend改为spending都可以。

spend多余了，去掉就对了。

更坚决的可以说： I have no much time for you.

i don't want to spend time on you a lot!

I can only spend less time on yourself.

反过来说也可以的，我举得你说的有点不对
