Which one is correct?
1. If you ever doubt the wisdom of your decision tell me about it.
2.He might doubt the wisdom of his decision.
So, you think that better choice will be the second?
As long as you didn't want them to mean the same, yes. The second is a naturally better sentence.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
And are there any differences between them?
I'm genuinely interested in your answer because we get this question occasionally. What is your understanding of two sentences meaning the same thing?
"In any differences" I mean not pronouns there are used but grammatical part. (gramatical structure).
