I hate my husbands job

Not anything we can do about it, it’s what he does but it just sucks. You all know how much selling cars takes from your life. He frequently gets the deals late at 8pm when he’s supposed to leave work. Then won’t get home till about midnight. I’m at home alone with our son all day & it just really sucks when I’m looking forward to 8pm only to have him text he’s with a customer. Like why can’t these sales be during his all day work shift instead of right at the end?! It’s just frustrating & I feel like a single parent. I wish he could find something else that paid just as well. My ex sold cars too & rarely ever left work late & if he did it was only by an hour max. The whole process to delivery never took as long either. Same dealership too. Sometimes my husband will spend all day like 6+ hours with a customer & then it won’t sell. I guess my ex just knew better not to waste time with anyone.
