wished /
acted as ifI know that
'I
wish I
were you' implies I cannot be '
you' and it is a kind of Conditional 2.
'He
acts as if he
knew all' implies it is not true that he knows all and it is also a kind of Conditional 2.
What I want to know is that
'I
wished I
met you' is possible to use and it is a kind of Conditionals or it is a past version of 'I
wish I
meet you'?
'He
acts as if he
knows me well' is okay to use and then how about 'He
acted as if he
knew me well'? Is it a kind of Conditional 2 or just a past version of the first sentence?
He
acts as if he
knows me well. ( it is likely for him to know me well )
He
acts as if he
knew me well. ( it is never possible for him to know me well)
He
acted as if he
knew me well. ( Which meaning is implied, likely or never?)
He
acted as if he
had known me well. ( Which meaning is implied, past or more past?)
I feel like my question this time is somewhat confusing to read but I hope that you can understand my point and please, don't be irritated with this question

Thank you so much as always and have a good and safe day.
