What should one do if ones husband does not support one

Asalamualakum
I am a marrid w0men age 37 with 2 kids. My husband does notsupprt me and the kids. He makes me beg him 4 money . He does have a business but the business not doing well and he refuses to go out and work. I had to find a job and since – earn he hardly ever contributes to the food or buy the kids clothes thus does having a great impact on our relationship. For the pass 5 years we don’t share a bed n constantly fighting. At the moment we seperarated and to be honest I don’t want him back as he put me through a very tough time please advice as we don’t have a mariage left I come from work and still got to do the householdchores which he don’t assist in anything. He does not help assist kids homework as well. He just sits and laze around. I am s0 frustrated – don’t knw where to turn n wat to do. Jazakallah
