How can one partition a list based on a given pattern?

For example if I have the following list:


and i need to partition this in {a,b} - to pair one 'a' and one 'b' as many times as possible within the list so the result is:


Basically i need to know how many accurances of {a,b} exist in the list, even a number saying (2) in this case works great. There are two accurance of tuple {a,b} in this list.

Any suggestions on how one might approach this problem?


PS. 'Tally' function might come handy, but i couldn't really utilize it.
