Want advice to for divorce or medical treatment.

Since day 1 of marriage i have bee observing my hubby's behavior which is not normal. He has strange behavior, sleeping single with many tools beside him. Ignoring wife, knifes collection. We just had intercourse for twice or thrice in this six years. Hubby is working in IT company, i thought of office problems, project change which is true but he is mental ill. He dont have any illegal affairs, Don't expect single money but don't let me to mingle with anyone he is the only person with whom i talk and rest my mother and sister in phone. Always lives in past, criticizing, we stay in separate rooms as their parents. I lost patience. I thought if i have kids both will be happy. I have asked several times. He refused to take any step, i gave many options artificial methods, adoption but he refused. Last year in 2021 i stayed at my mother's house for 6months but nothing change same thing is repeating here. I know nothing will change without treatment which he is refusing.
