I'm shocked you didn't immediately show him the door!
What an arsehole!
"He said it wouldn’t be fair if i decided to leave him and took him for 50%" why the HELL would this not be fair?!
He may even be hoping that this will lead to you calling off the wedding, but not ending the relationship.
My understanding is "no contract can negate the law of the land" so he can't stipulate that it leaves you worse off than a normal divorce would.
On the other hand IF you decide to proceed if I were you I'd ensure certain codicils were added:
1 acknowledgement and suitable settlement to account for YOUR contribution to "his" savings that he was able to accumulate as a result of your sacrifices
2 immunity from any debt HE incurs
3 an agreement re keeping housing for the children in the event of a splits
4 a fidelity clause! He wants to go all legal fine! Works both ways, if he cheats there's a penalty! (Include emotional affairs, registering on dating sites etc)
5 a "good husband" clause - minimum standards of certain behaviour or else there's a penalty (you could have real fun with this one I'm sure we could help you come up with a long list!)
In all honesty he sounds a shitty selfish piece of work who cares more for "his" money than his family!
I too am sick of being accused of being old fashioned, smug and judgmental for saying on repeated cohabit v marriage threads ESPECIALLY where the woman is considering or has become a sahm or working pt that it's foolish not to marry BEFORE having kids or at the very least BEFORE quitting full time work!
"If they hadn't of married, she would have got half and more, because legally you have the same rights when there is children" not true in the uk are you referring to a different country?
We haven’t got married before now because he’s always said he doesn’t have the spare cash and he wants us to have a proper wedding. Also neither of us were that bothered, but then i started realising it was putting me in a very precarious situation should something happen to him
That strongly suggests to me he wouldn't be marrying if it were up to him - precisely BECAUSE he views it as "his" money and knows marrying legally changes that. The guff about not having the spare cash is just that - guff!
Secrets about money, lack of honesty on why he wouldn't marry, dropping this on you 8 weeks before the wedding...
Doesn't sound like a great relationship to me!
