Need advice

Namaste, I am married from last 8 years & have seen many ups & downs in my marriage. Me & my husband are staying together & my in laws are staying in the outskirts. We visit them regularly. From last one year I m at my parents place as I was pregnant. During my absence, my husband has been regularly drinking, smoking & whole day watch movies etc... living life like a spoiled bachelor. He has more then 40 lacs of loan also from the market & hardly give any money to me. Emotionally also he has been abusing me & never cared for me even during pregnancy. If I say something that I know you have been doing all bad activities there ....he says where is the proof. My mother in law is also trying her best to break this relationship. She is using some black magic kind of things to create fight between us so that we gey separate. For that also I don't have any proof. My parents and my husband & in laws are in two different cities so we can't catch my husband red handed & I hve no proof except few people who called and told me what all is happening there in my absence. Now I am worried that if with my small baby I wll go there ...he wll again emotionally torture me & what future he will give to my baby. My mother in law also is creating multiple fights between us. I am so confused what to do. In all these the kid will suffer. Shall I file for divorce or keep bearing all this? Please advice. Thanks
