I’m so sorry to hear this! This all just doesn’t add up to me, in my humblest opinion. You’re a SAHM, taking care of everyone (including the house I assume?) how and why do you have to go 50/50? And how is he not showing up as a dad and husband? You need to have a serious conversation with your husband. And please, take care of yourself. Remember, if your glass is empty, you will not be able to pour into your kids’
You’d be surprised , when you leave for a weekend he’ll probably care for them well enough but relies on you and acts useless to get you to do more. Sounds like a lazy guy.
I’d say leave him with the kids but have someone on stand by? Or have him go to family with them so u can make sure they are looked after
