Regex to find the string from the word ending with "ing" and before the fullstop (.)

Hi,

I have the following string "This is my text string I know. I am loving it I know." I needto find the string from the word ending with "ing" and before the fullstop (.) so in my sample I need the output as "string I know" and "loving it I know". How can I do it ?

    static void Main()
    {
        string input = "This is my text string I know. I am loving it I know.";
        string regex = @"([\w]+((?<=\w)ing\b)).+?(?=\.)";
        var matches = Regex.Matches(input, regex);
        foreach (var match in matches)
        {
            Console.WriteLine(match);
        }
        Console.ReadLine();
        //Output
        //string I know
        //loving it I know

    }
}
