There's infinite universes in the multiverse... but only 53 of them are in a sense, near identical. Barry Allen of Earth 38 is pretty different than his Earth 1 counterpart, he is a bit older than his other version, being Flash for almost 4 years, he was adopted by another cop named Darryl, Barry tried to a few times to be in a relationship with Iris West... but it was near impossible... she wasn't the one for Barry. He became Flash at the age of 24, and in 4 years, he is being called as one of the most famous heroes on Earth, Scarlet Speedster and Central City's Guardian Angel... he could have anything... he could... but he decides to take a break... across his 4 years, the only thing he has met with is with pain and regret... he takes some vacation to National City... but his past just follows him.
