Marriage after filing for AOS

[Lonesome Dove]

I filed my AOS application with CSC on June 15. I am single and
need following information.

1. Can I get married now and add my spouse to my 485 application

2. What is the last stage after which addition of spouse is not
    allowed. Someone told me that I can get married and file
    a 485 for my spouse anytime before my 485 is approved

3. If the above information is true, is there a way to delay
   the approval of 485 application until I get married.

  thanks for all the help,

One way you can delay is by postponing your FP. I think if you appear for the fingerprinting, then you cannot delay it further.
