Evening Toots. How's things in the slightly more west West Midlands?
Being frustrated is normal. When I ask people relatively straightforward questions which require an answer and they don't give it - its frustrating!!! Its how much we let that bother us or affect us that we need to concern ourselves about.
I find adopting a default position helps, and I don't mean in a standard revert to way I mean more of a 'I will take the absence of an answer as.....' Way.
For one of my work things I've got to corral a whole load of uninterested people and get them to agree. I only really made progress when I openly adopted the policy that silence or absence will be taken as explicit agreement with whatever I decide. Suddenly they started engaging.....
On that front I don't think your options are as you are or file for divorce, you have an alternative in being more forceful in pushing the finance. So you could email him and say
'I've asked my solicitor to start drawing up a financial agreement so we can proceed with selling the house. If you have any particular views then let me know, if not I'll get a draft to you when we have something'
If he can be entirely passive should he choose and you still start progressing only the things you want to progress. Just a thought so feel free to ignore me.
Good luck with the interview. Is the presentation done? You'll be great and ace it I'm sure, but if not as everyone seems to agree with you I'm sure you can get a job as deputy prime minister!!!
