Remember that even your points appear to be valid, two things have to be kept in mind. If she filed divorce on the ground of cruelty, then she left you in 2013 or 2015 won't matter that much. If her case is on the basis that you deserted her for more than two years, then her petition will be dismissed, if you prove that you both statyed together (really cohabitating) till 2015. Next, even if she mentioned wrongly about the place last resided together, if the place from where she filed the petition falls within the four categories - the marriage took place in that jurisdiction, or last resided together or you are living there at present or she is living there at the time of filing the petition, then that court has got jurisdiction.
