Help on unreasonable behaviour on form D8

Hi all, i'm a little stuck on this bit. The side notes say: Behaviour cannot be used if you lived together as a couple for a period, or periods, totalling more than 6 months after the date of last incident you want to rely on as evidence.

The situation was that we lived together for over 2 years when in fact the marriage was over. We didn't have a sexual relationship but did still sleep in the same bed (we have a v. small house and the 2nd bedroom was used for storage & other things). There were lots of reasons for unreasonable behaviour. My husband was sectioned as he was psychotic and later diagnosed as Bi Polar, this led to situations such as alcohol abuse, sitting up till early hours of morning watching politics, singing along to music and keeping me awake when I had work in the morning, in bed for most of the day because of previous nights antics, not going out of the house at all (not working) all my social life was with friends and never with him, and also he went from being an athiest to a born again christian, I do not share his views.
My question is, as there wasn’t actually one set incident that ended the marriage it was an accumulation of incidents, how do I provide correct info as a case for divorce?

Apoogies for long post

You would need to cite 5 different incidences/examples that occured during the last 6 months you having lived together as a married couple when writing your statement of case.

If you need help with writing the petition, etc, call the helpline on 01202805020.

thank you
