Thank you all - I appreciate all your feedback. I'm flipping between the two trains of thought being offered on here to be honest.
I'm in a better state of mind today than I was yesterday. It's possibly down to the call he got from work.
He's a trustworthy person in general (as in he doesn't lie/cheat etc), but I know his actions recently haven't been trustworthy (i.e. Leaving his job so abruptly & apparently without any thought for his family or my opinion on the matter).
He's a very charitable man & will do anything for anyone to help them out & doesn't expect anything in return (except doing housework or childcare for us!) I know I've made him out to be a shit & I suppose his recent actions have supported that theory! But he's always trying to do things for the greater good (the business idea reflects that - I'm afraid I can't go into too much detail about it as I don't want to jeopardise it now that I've ruined his fan base
)
I'm not trying to defend his actions as I know what he's done is highly irresponsible & the way he spoke to me (his pregnant wife) last night is close to unforgivable, but I feel like it may have come from a place of deep stress & anxiety on his part. It'll take me a while to push it to the back of my mind, but his words & actions since have been much more "sane".
He's open to talking to his employer, as they've requested, and he's open to negotiating with them if that's what they want. He'd like to come to an arrangement that means he can get even a part time wage from them & work on the business the rest of the time, or be appointed at a level more relevant to his experience (he was promised a promotion, but they pulled out & denied promising him the role - that manager has since left)
Some more background (sorry for drip feeding!) - he already took out a grievance against his employer due to the bullying, but nothing much came of it as it was an internal investigation & was flawed. On appeal, it was discovered they didn't follow due process with regards to the investigation so it was totally flawed. The process went on for close to a year so, to avoid any further stresses (ironic now!) he decided to just leave it if they offered a letter of apology, which he got. He was seconded out of the "toxic" environment, but was moved to a location a long commute away, so that has added to his stress & of course means less time to put into the business. And he's still bitter about not being at the level he should have been appointed at. The "bullying" claims did all start from not being given that role & then his time keeping being monitored (he felt the two things were linked - I'm not sure)
He's already made good in-roads into the business - has built strong contacts, potential clients, is on the steering group of a business forum that meet monthly etc.
Some may think I'm defending him here. Some may think I've been unfair to him not mentioning all this before. But as you can see it's a lot of info & I felt it irrelevant at the time of writing my previous posts, because the reality is still the same - he's left us without a wage at a very vulnerable time & there's still no guarantee that the business will make money. There's nobody more driven, passionate & dedicated to making it a success than he is. He's doing all the right things (business wise) so I can't altogether blame him if it does ultimately fail, but I still feel incredibly nervous & untrusting with regards to him leaving us without an income at this time.
Being unable to pay my parents back is also a huge burden for me, but he seems less bothered, which also annoys me. He's almost unappreciative of their loan (a huge amount to them)
