Don’t want to be a sahm

I’m already a stay at home mom have been only for a few months. I’m about to have another baby and I don’t think I want this to be my life. I want to go out and work because no work from home job pays enough. My Bf works outside the home and can always go wherever he wants and I’m sealed in the house with a baby. I never wanted this to be my life I never dreamed of being a mom that just stays home. I need to go out and wor, I’m not sane here at home
