I'm trying to figure out why it is, when I close one form - which is supposed to set a property in my Main form to true - the property reverts back to false.

private void OK_Click(object sender, EventArgs e)
        {
            //use this to confirm that the user is valid
           Main userAuthentication = new Main();

            userAuthentication.AuthenticUser = CheckUser();

            if (userAuthentication.AuthenticUser)
            {
                this.Close();
            }
            else 
            {
                if (Tries < 2)
                {
                    MessageBox.Show("That was an invalid user name or password. Try again...");
                    ++Tries;
                    CheckUser();
                }
                else
                {
                    userAuthentication.AuthenticUser = false;
                    this.Close();
                }
            } 
        }

        public bool CheckUser()
        {
            //testing number of tries
            //string numberOfTries = string.Format("tries = {0}", Tries);
            //MessageBox.Show(numberOfTries);

            if ((usernameTextBox.Text == "User1") && (passwordTextBox.Text == "User1"))
                return true;
            else if ((usernameTextBox.Text == "User2") && (passwordTextBox.Text == "User2"))
                return true;
            else
            {
                usernameTextBox.Text = "";
                passwordTextBox.Text = "";
                usernameTextBox.Focus();
                return false;
