My Spouse Fled Country Leaving me and my 5 year old in the US

I came to Texas, US, in 2017 on H4; I was in an abusive relationship, which got worse over time. I got H4 EAD in February 2022, and I battled stage IV Cancer from 2022 Jan to April 2023 ( My husband is done with me- used to say I'm a burden). In August 2023, following a DV situation at home (He spat on me, pulled me by my shirt out of the kid's room, tried to hit me, and threatened to break my legs), my colleagues at the workplace helped me file a police report against my husband. He was threatening to deport me, and he also had moved all the money out of the joint account, which exhausted my option to hire an attorney immediately the free legal services were taking a long time to hear back from, I sought help from woman’s organization and as I was mentioning an incident where my husband put my 5-year-old child in the corner of the room without any clothes straight out of the bathtub ( this happened in August 2023 too) they said they are mandatory CPS(Child protection Services) reporters and they have to report. In 2 days, CPS called me and asked me to leave the house in the middle of the night. Otherwise, they said I would also be counted as a perpetrator. I went and stayed with my senior colleague; she helped and supported me until I found a new apartment. Since I moved out with my child in October 2023, my husband never made significant efforts other than a couple of text messages to ask about the child ( This communication felt like he wanted to show something to the CPS that he cared about). I believe he left the country and messaged me saying he did not intend to return. There is an arrest warrant for him as of November 01 but I believe he fled right before that, and CPS ruled out "Reason to believe " with him as Perpetrator. My Spouse's home base is Mumbai and I want to file for divorce in Texas (I have my cancer post scan and port flushing pending here, in addition to that our kid goes to school here and we have a life here). I'm not in a position to return to India. I want to serve him the divorce paper in Mumbai, I spoke with an attorney in Texas but before we filed he fled the country. How do I serve him?
