E-mail Filed population with autro delete when boolean unchecked but keep the other data

Hello, All.
I as am recently new in InfoPath (2013) I would like to ask you for the following:
I have created a form in which there are several number of booleans (check boxes). I have also created data connections to a SharePoint List. And also I have a multiple line text box.
The Idea is:

1). When the check box is checked it must populate the field below with the e-mail

2). When several check boxes are checked the string should add those additional e-mails to the string filed.

3). When a check box is checked and then unchecked again it should delete ONLY the e-mail which this check box is representing, and not to delete the other ones.

Hereby the Action rule that I have:

Checkbox = TRUE

-> Action

Set field's value:
Field: = emailSummary (multiple text box)

Value: concat(emailSummary, E_x002d_mail_x0020_address[Function_x0020_Area_x0020__x002f = "Delivery"], "; ")

I would really appreciate if you help me with that issue (I believe it will not be hard for you) :)
Thank you in advance!
