Separating Out Address Using VBA

I have a spread sheet with thousands of addresses in them.

It does not hold the state however.

I need to separate each part of the address into it's own cell on the same sheet.

Keeping the first part ONLY of the address in the original place the address was in.

However not having the city, or zip in that cell.

For example:

E2 holds the address: 19505 45th Ave. W. Suite A, Lynnwood 90821

(There is always a comma before the city. However sometimes there is another comma before Suite...)

I want the end result to be:

E2: 19505 45th Ave. W. Suite A
I2: Lynnwood
K2: 90821

Then I would like it to loop through all the address's in the "E" Column until it has edited all the address's. It is sad to say but I have been working on this for over 48 hours... Can't believe no one online hasn't come up with a clear answer on how to do this. At this point I am looking for the code to make this happen in Excel VBA.
