Walking alone😒

I'm 36 weeks nd 5 days nd have been told to walk a lot. It's kind of hard cause it's been too hot but at night it's been fresh lately so I told my bf lets go walking at night. He will tell me yeah then once it's night I'll tell him lets go nd he doesn't want to go cause he's too tired from work. I would go by myself but I low key get scared lol he water the grass when it's sunset still a little fresh outside nd told me to just walk around the house while he has the sprinklers on but I don't want to look like a crazy lady walking back nd forth lol
