Okey so he won't propose to me and he never marry me .
Yes, that is the overwhelmingly likely case.
Which is why it's madness to not be getting yourself financially more independent as quickly as humanly possible.
Because at this stage, he could simply break up with you and you'd be left with half the equity in your home (you think) minus his ringfenced repost, plus CMS payments from him each month.
He has no legal obligation to provide anything else but you have enabled him to continue earning, saving and having enough money for his hobby throughout the course of your relationship. He's been able to do that due to the childcare you provide your shared children.
You've taken a huge risk and it would be sensible to now start behaving accordingly and get back to work, with a plan of action to become independent, rather than continuing that huge risk with a man who has shown you that he's happy to string you along.
And, importantly, who views a proposal as a reward (bleurgh) for women, something he'll give you if you stop 'nagging' (I bet he loves that word) and stop discussing... rather than decent blokes who propose because they actually want to marry the other person.
