Husband is not willing to provide expenses for Child's upbringing

Mine is Catholic wedding. after my sons birth my husband was calling me back to stay with him. Since we both r working I told him to request his parents to take care of our son in our absence. But my husband said that he spoke to his parents but they r not willing to take care. Then I told him to take a rental house near my parents house as they would look after my son. But he was not ready for that. And was forcing me to either leave my job or keep son on babysitting. financially we r not stable so I cudnt leave my job plus so many news I hear so I was scared to keep my son for babysitting. and so till now my son is one year old but m at mothers place. but The problem is that he is not willing to share expense of the child. Not even a penny he has spent. So m I right in asking for half money for child's expense.
