If you want to stick to a regex based solution.

>> str = "one one one. two. three."
=> "one one one. two. three."
>> str.scan(/\w[\s|\w]*./)
=> ["one one one.", "two.", "three."]

And you could keep going adding more words in the same pattern

>> str = "one one one. two. three. four. five."
=> "one one one. two. three. four. five."
>> str.scan(/\w[\s|\w]*./)
=> ["one one one.", "two.", "three.", "four.", "five."]


It may not be the best solution to this problem, but it is always good
have your regexp skills up to date ;)
