In India, you are NOT yet safely treated as divorced because the Indian court has not recognized the German decree and the Indian divorce case is still pending. Your marriage was originally governed by Indian law.
If you remarry in India without resolving this your second marriage can be challenged as void, you could face bigamy allegations under Section 494 IPC, the marriage registration authorities may refuse registration and you may face future legal complications (property, spouse rights, children legitimacy).
She remarried in India after German divorce, but that does not automatically make it legal under Indian law.
If the German divorce is not recognized in India then her second marriage may also be legally questionable, but unless challenged, it may continue practically. As a matter of fact, she too would face the similar situation since she got remarried during the pendency of divorce case in India.
Therefore to safeguard your interest you may file a suit for declaration to declare the German divorce as legally valid under Section 7 Family Courts Act read with Section 13 CPC, but before that you may have to withdraw the pending divorce case citing this as the reason.
If she cooperates you may file joint memo in Indian court accepting German divorce, court may dispose the case quickly
