Husband is threatening me advice pls

My husband is arguing bcoz im sending my 2 year to pre school for just 9 hours a week free of cost. He said i am a useless woman who just sits at home and do nothing (i am a stay at home mum) so i should gv more time to our son and if i still send him to preschool i have to leave his house. Any suggestions and thoughts? I have just one child i dnt think i am doing anything wrong here and he thinks he can threat me instead of taking abt his son its for him not me and i do al house work clean cook like a maid still he says i do nothing and he earns! Every Friday and Saturday he goes out at night until 3-4am and i am alone with child at home and he is telling me about giving more time
