What is the procedure to file for a Divorce petition?

Main West Bengal se hoon aur meri shaadi 2022 mein Special Marriage Act ke under hui thi. Main Hindu hoon aur meri partner Muslim hai. Abhi bhi hum dono alag-alag ghar mein reh rahe hain. Lekin pichle 2 mahine se meri partner mujhe cheat kar rahi hai. Usne 24 ghante mein se 5 minute bhi baat nahi ki, na call karti hai, na kuch aur. Bas keh rahi hai ki mujhe chhod do, jo karna hai karo, aur bhi bahut kuch. Hum pichle 8 saal se is relationship mein hain. Ab main aise situation mein hoon ki na main kuch kar sakta hoon, na wo ja sakti hai. Is age mein meri life kharaab ho gayi hai. Kya iske liye koi insaaf nahi hai? Kanoon ke hisaab se kya hai? Kya kisi ki zindagi aise hi barbad ho sakti hai? Main ab suicide ke vichar mein hoon. Agar koi solution hai to batayein. Main aapke channel ko 4 saal se follow kar raha hoon aur ab lagta hai life ka raasta kho gaya hai. Kuch ho sakta hai kya?
