I missed a page - stay strong!
He does not care about you, about the baby, or about the dog.
He has brought up the dog 'issue' because he knows it causes you anguish and because if you give in it will show him the power he has over you. He will keep on cracking the whip after that - it will not end with the dog.
His reference to buying your maternity clothes shows his contempt for you, a lot of anger towards you personally, and anger towards women as a class. He thinks your relationship should be all about what you do for him. He thinks women are beneath him and their concerns contempt worthy.
The references to his tea and cleaning are in the same vein - his opinion of what he is entitled to, and no concern for your welfare.
He deeply resents the fact that you are breastfeeding (aka sitting around all day) not because the house is a tip, which it is not, but because your attention is on the baby. He is jealous.
Has he actually left?
If not, he must leave. Please call the police if he ever again says he will take the baby and you must choose between baby or dog. Legal advice my arse - he is trying to bully you.
And call Women's Aid TODAY.
This man is completely unreasonable, and dangerous.
