I just typed a whole page of a response, but then changed my mind.
Insead I'll just say this -
If you were with my borther i'd say run a mile, fast.
He had his own business, he was a very 'high functioning' stained glass artist, he made a fortune, then drank it, then told his wife she'd be more fulfilled etc having a good job, then when she got one he drank her wages too.
There was even a point where he cleared their sons savings account, he drunk that too.
You wouldn't be with him though, he lost the battle almost two years ago. He left a son (that would be sort of equivalent to your future babies perhaps?) who he'd physically and mentally abused for a couple of years.
A different slant I know but we thought he was 'just one of the guys' off to the pub after a hard days work.
When we were forced to look at reality we all knew deep down that wasn't the case.
I wish you well and I hope you and your man are some of the lucky ones.
