I have a yard service that takes care mowing, and they don’t call me in advance to tell me they are coming, so I wouldn’t expect your H to give you advance notice as long as he isn’t coming into the house (garage doesn’t count).
Me: 44 H: 44 Kids: 20, 16, 16, and 10 Together/Married: 22 years H announced he was emotionally detached and considering D: 4/4/16 H announced he is going to try to stay and reconnect: 5/1/16
