How to tell my bestfriend Shes too hovering ?

So my bestfriend is starting to get really annoying. I love her to death like my sister. But We arent in high school anymore when we use to talk on the phone for hours or just breath on the phone you know how us girls are. I have a 1 year old and Im 6 months pregnant and Im married so my life is not the same. She expects us to talk

on the phone all day text all day... and I dont talk to anyone all day... i just be in my own little world. Of course we still hang out and talk every day but i cannot talk alllll dayyyy long. I can be having alone time with my husband she calls, family time, she calls Ill tell her ill call her later 40 min later she calls back. i went to see my Godson the other day hes 2 months she texts me like im inconsistent. I told her already i was spending time with my Godson. idk how to say it without hurting her feelings. my husband is like “Damn she dont got a man or sum?” I know im her only friend but damn i need a break.
