HELP A FEW QUESTIONS

1. Married 1998, two children
2. Unreasonable behaviour is the reason
3. Have been existing in the same house for several years, effectively living apart, with minimal support. Two children, one now 22 and the other 17.
4. Have had serious medical problems over the last 8 years through depression resulting in hospitalisation with kidney failure. Have suffered with problems coping which led to misuse of alcohol and over the counter pain killers. Have been hospitalised three times, recently (mid-June ’21) after two seizures induced by alcohol and over the counter drugs.
5. Key reason for depression is the relationship, living in a home which is a basic dumping ground for loads of stuff, which meant I tried to escape by living for most of the time in my room.
6. On September 2nd 2021 started living in my parents house, after reaching a rock bottom and feeling suicidal. Have improved but still in recovery supported by professional help (I-access).
7. Have had no support from my husband over the last three years.
8. Suggested counselling to my husband several years ago but he refused; now feel that it is too late for any reconciliation but would consider this if it would help. Basically I feel the only sensible way forward is a divorce.
9. I have no idea whether my husband would take an amicable route or would he try and delay proceedings, be difficult etc. He is a strong catholic and does not believe in divorce, it would create difficulties with his mother. Because of this he is very unlikely to initiate divorce proceedings.

Current questions?Would unreasonable behaviour cover this for grounds for divorce?Should I now tell my husband that I want to start divorce proceedings and how should I do this?Assuming starting now when is a divorce likely to become absolute? Would it be worth waiting for the “No Fault Divorce law” to become active? (Currently April22 being mooted ?)What is the situation regarding my living with my parents? He is not supporting me with anything?Who pays for the legal advice associated with the divorce?
