What legal action can I take after no reply of legal notice?

Hello Sir/Madam, I have already issued a legal notice to my husband and in-laws regarding domestic cruelty and mental harassment. They are falsely accusing me of having an affair based on old friendly chats and one message I had sent in anger saying, "I'm characterless" — which was never true. I was sent away from my matrimonial home during pregnancy. Even after the delivery, neither my husband nor my in-laws took any responsibility or inquired about me or the child. I have taken this legal step to protect my dignity and secure my daughter’s rights. Now, I would like to know: • What should be my next legal step? • Can I proceed with filing a Domestic Violence (DV) complaint? • What if they try to file false counter-cases against me? • I have already sent them a legal notice. They met my advocate personally and stated they are not willing to take me back. My advocate suggested a common meeting at his office, but there has been no response from my husband or in-laws since then. Thank you.
