The woman suing Kyrsten Sinema for allegedly breaking up her marriage has questions about her ex-husband's conversations with the former Senator's legal team ... and she wants a judge to make him answer them ... TMZ has learned.

Kyrsten's boyfriend, Matthew Ammel, was recently deposed by lawyers for his ex-wife, Heather Ammel, in her case against Sinema.

Heather claims Kyrsten's lawyer was present when she grilled Matthew about his relationship with the politician. During the depo, Heather said Kyrsten's legal team objected to some questions being asked on the grounds of attorney-client privilege, claiming Kyrsten and Matthew's lawyers had an agreement to work together in the case.

In her filing, Heather claims Matthew's story about his romance with Kyrsten changed to be more aligned with Kyrsten's version of events.
