I need to vent..

So ive been with this guy for two and half years now.. We have a four month old daughter and im pregnant again. i also have a 4 almost 5 year old due to a past relationship. They adore one another he has taking my son in as his own. So he wants me to be a stay at home mom which im not complaining. I love it. We have our ups and our downs. But He has been a bit possessive these past few months. Kind of driving me nuts. And he doesn't want me working at all 🙄 we argue at it some times. BECAUSE he holds money over my head and i just want to punch him in the throat. Esp. That he wants me to he a stay at home mom. For example My daughter has a whole 6 diapers left. And its a god damn obstacle to get money out of him. Which he makes 700-800 a week. Him making that amount a week, she should not be running out of diapers. Im not crazy for being upset am i ?
