Questions on English grammar
1.What's the difference between "it's difficult to me" and "it's difficult for me" ?
2.What's the difference between "I like to learn English" and "I like learning English" ?

Question

Answer

1. We don't normally say 'It's difficult to me'.  The usual construction is 'It's difficult for me'.

2. There is no significant difference.

Answer

I agree with the previous answer.

You might hear someone say "it seems difficult to me" or "it feels difficult to me" but those are slightly different constructions, although with a similar intent.
