Husband threatening to take child away

Dear team, I am married for 8 years now and a child boy of 7years . This is my 2nd marraige.i have a daughter from earlier marraige she is 14years old. My husband has taken lot of loans from bank and outside which has even crossed his ability to pay out of his monthly salary. He has done all this without keeping me informed or having discussed with me. He has taken top ups on home loans , personal loans , money from friends etc but has not shared any details to me. He is now forcing me to take loan and give it to him so he can make more money out of it but he is not sharing any details. He has forcefully put my name as coapplicant in home loans and top.up loans even though i was not willing . His behaviour is not good at home . He keeps on fighting on pity matters and keeps on threatening me everytime that he would leave me if i wont listen to him and he would also take our son away with him. He also says he won't take any responsibility towards me and my daughter and wants to go and live seperate by taking our son away from me . I was not working for few years but recently picked up job as work from home to which he continuously troubles me , doesn't allow me to work and keeps threatening me to quit the job as he doesn't want me to be financially independent. He puts me in a false allegations that i cant take care of children if i work but which is not case. He had even stopped givibg any support to run House hold expenses. Another important fact is we are living in a house bought by me to which small portion emi is still outstanding which he would support by paying considering as a small rent that he would otherwise pay. Now he says he would even stop paying for that . He too has a 3 1 bhk flats which he has given on rent. He wants to trouble me in every aspect. Pls advice Can he forcefully take child custody with him? Abd any other advice ...thanks team , dear member for taking your time to advice me on my issue.
