Need advice..

My husband and I haven't been on a date in a while.. Its not that we can't afford it.. The problem is, is his mom.. We live with her because she can't afford it without us. When I ask my husband to take me out for supper she throws fits.. Makes us feel we can't be husband and wife and enjoy ourselves.. We make supper and its to the point we have to put it on her plate and serve it to her.. I feel like a maid. Any suggestions?..
