He likes a lot of sex so you ‘guess’ you enjoy that.
When I read that it reads like it could have been written - he likes to go fishing at weekends, so I guess I enjoy that
or he likes a lot of macaroni cheese for most of our meals together, so I guess I enjoy that
or even - he likes me to put a strap on and call him Martha while dressed as the tooth fairy, so I guess I enjoy that
Do YOU actually enjoy that or do you say/ think you enjoy it as much because you love him and that’s what he prefers?
Why would he marry you when he’s got you exactly where he wants you, for free?
Free childcare, free sex, free meals - and it sounds like it’s all served up with a pleasantly grateful smile on your face.
I’d give him and ultimatum or plan a weekend away with friends or family so he has to look after his own children and cook for himself while you’re away. He may realise he’s got a lot to be grateful for.
That’s if he isn’t then lovingly ‘protective’ and stops you doing that.
