My husband abandoned me and my kid

My husband and me are separated for 5 months now. In laws are falsely accusing me that I asked their son to leave them. I heard that he is getting a new home. So I went I his home and they locked it and went out knowing that I m coming. I stood there in front of their home at 8 PM WITH MY 5 year old son. I am called my husband and my MIL took the call. I started explaining her that I didn’t want to separate her and her son. I even said I will fall at their feet. I even made my son to talk to my husband. He avoided him. My mother in law falsely accused me that I ran away after two days of my marriage. I was not able to hear those words I disconnected the call and came back to my home. My mom is a single mother. She made me study and get married to the person I love. She gave them so much. In fact recently she registered a land in my husband name. She is 64 now. Retired government service. I can’t depend on her. I m helpless.
