If I prepared a document on behalf of dp supporting his side of divorce

[objectivity]

Which was I under pressure to do and was full of lies could I inform legal parties that this happened and what would happen as a result?

It feels like that solidgb but I have allowed this situation. It has been my fear of abandonment, of being homeless and going back to a refuge that has made me cling on to the crumbs he has thrown me. I've even asked him to come and spend the night with me, so it is partially my fault.

Yes,I am concerned that legally I could be in trouble too.

Get some legal advice from CAB or Women's Aid. You are being ABUSED and EXPLOITED by this piece of shit and it is NOT your fault. Abusers like him rely on your fear and guilt and unhappiness to let them get away with their shitty behaviour.
DOn't bother dealing with his wife, she is probably in a headfucked space as well, this man is really nasty and dangerous. CALL WOMEN'S AID.

how did you get on today?
come to any decisions?
