Hi,
1.I’m so sorry to be so hard on you.
-Why don’t we use “to” instead of “on”? It's diificult to find a good reason, but that's what we say.
2.We recently spent 30,000 USD for her to go to a boot camp to straighten her out.
-What does “straighten her out” mean here? To remove her problems.
3.I will either find it on sale or go without it.
-“go without it” means “forget it”, right? Yes. It means I will continue my life without it.
4.Just keep loving and admiring him for the good you see in him.
-"for the good………” here means “ for good qualities……..”, right? Yes, that's what it means, although 'good' here is a noun, not an adjective.
5.Is it top late for me?
-This means “Is it too late for me”, right? "top late' makes no sense. I'm sure it's a typo, should be 'too late'.
6.I don’t think I can take much more of this.
-This means “I don’t think I can stand anymore of this”, right? Yes, except 'much more', not 'any more'. I can stand a little bit more.
Best wishes, Clive
