There are a lot of questions about lookbehind, But I couldn't find my answer.

My RegExp with negative lookbehind is working fine in chrome but not in IE.

I need a regular expression that match any word after a period(.) but there should not be a (Mr) before the period. for example in

'I met Mr. Jack this evening. He is a good man', but honestly Miss. Jackson, I am for real.

I want to get He, but not Jack (since it is followed by Mr.)

so far I have comeup with the mrs. Sullivan regExp which works fine on chrome, But it doesn't on IE. and It is to be run on IE.
