Greetings. Let me answer your questions one-by-one:
Yes, your spouse can object or dispute your absolute divorce by saying that you have not been separated for at least one year. If you have a separation agreement, the spouse could say that you either did not separate before, contemporaneously with, or shortly after the execution of the separation agreement. Or, your spouse could say that you reconciled after the date of separation, which would start the clock running again for the one year separation prior to obtaining an absolute divorce.
The Separation Agreement, if executed properly, is binding on all parties regardless of whether or not the parties divorce.
Breaches of a separation agreement do not affect filing for an absolute divorce. Owing child support does not affect the absolute divorce.
Best of luck.
