The blood sample issue was sorted out, so his case was brought forward to last week. (We are now separated, but seeing as some of you have been such a support to me I thought I should let you know the outcome...)
Sentence was all of the following:
16 weeks prison sentence suspended for 2 years
150 hours community service
Additional 4 year ban
Up to 10 days Rehabilitation Activity Requirement
6 months Alcohol Treatment Requirement.
As I say, we're now separated - I just couldn't do any more to help him, and needed out. There's no way back for me, but hopefully all of the above will help him (and his new girlfriend, but that's a whole other story!)
Thank you again for your support - it made a difference in some dark times.
