house wife , how much should my husband pay me ?

So me and my husband recently got married . We're going into 1 month , but we've been living together for over a year and a half . I stopped working this year in January and was just focusing on school . My husband takes care of all bills . He is 29 and has 3 houses all valued at over 500k . I currently just go to school and while this year I was very busy with school and wedding planning now that the wedding is done and I'm only going to school part time I talked to him about me getting a job . He didn't like the idea of me going to work for a minimum pay and most likely would end up working evenings and weekends when that's the only time his home . So he pretty much said to give him a monthly amount . So that way I have money of my own to spend . He makes like 13k a month (he has lots of bills too though) 
How much should I ask him to give me a month for staying home and being a house wife ( I don't wanna feel like his paying me for the things I do because I do them out of heart ) 
I do keep our house very clean , his things are always done nicely and I pack his lunch , and always have dinner ready for him when he gets home . 
How much should I ask for myself a month ? 
Edit: We have a savings account together and all . The extra cash a month would pretty much be for me to spend on anything I want . Clothes , shoes, makeup
