Morning OP,
I was one of the posters a couple of days ago advising you to not discuss finances with him.
You're a grown woman, you'll rightly so do what you want, I respect that, but I'll say it again.
There is no need for you to talk finances with him at all. He might say one thing, then do another.
Your SHL will be costly, let them earn every penny by doing this for you.
You both appoint a solicitor, each solicitor meets with their client. They negotiate, go back to their clients, re-negotiate, until a deal is reached.
Don't give yourself extra stress and hassle,you have enough on your plate.
My ex used to ring me up with various 'offers'. "Sounds lovely, Tell your solicitor and he can tell mine'. After about the fifth time, he got the message. I got far more than the best deal ex offered me.For God's sake don't agree to anything!
You're paying a SHL a lot of money to get you the best deal. Let them.
Final bit of advice for what it's worth. Be the petitioner, not the respondent. File soon.
This man is not your friend.
