Alone time for SAHM !!

Ericka

My baby girl is 4 months and I have been with my daughter since day 1 I never really get help with her. I have been trying to get some alone time and go hang out with friends or just go over to my sisters house for quality time but every time I ask to go out it's a fight between my husband and I and even when he actually agrees to it he is constantly calling me asking where I am who I'm with what time am I gonna be home? Also if it's not him calling or texting me it's his mom telling me I shouldn't be out and I should get home ! Which leads to my alone time being filled with stress... should I be able to go out alone ? How often do you get "alone" time? Am I wrong to be upset by this ?
