I’m really shocked at some of the people saying OP is being judgemental and clearly doesn’t like her SIL. To me, OP is just setting the scene and creating a picture in great detail so that we can see how bad things are. Yet because OP is listing everything that SIL is doing that is of concern to try and paint a true picture of the situation, somehow that becomes “being judgmental”?! I mean, WTF?!
In that case, social workers are judgemental, as are teachers, and neighbours who report neglectful behaviours to the authorities.
What SIL is doing is not alright, in any way. What her husband is putting up with is horrendous. Put yourself in his shoes, for god’s sake, especially if you’ve ever had depression and held down a full time job at the same time. He has probably got nothing left to give at the end of the day, and why should he need to do the basic parenting she should have done when he was out at work all day.
I work full time and would not be impressed at supporting a “partner” financially while they did not work but neglected the kids to boot. It is totally grounds for a divorce, based on unreasonable behaviour. She is not his “partner”.
But he is between a rock and a hard place. There is no easy solution for him as if he divorces her in this situation the kids could well be worse off and neglected totally while in her care. As in left on their own in the house etc He is trapped and that isn’t going to help his depression.
However I think it’s something he should consider as this clearly can’t go on. Maybe that will bring her to her senses.
I bet the children would end up taken into care though and they would possibly look to the wider family first to place the kids with someone they know. That would be you, OP. Could you have the kids full time in a more formal arrangement?
You’re stuck really, OP. If you confront her about the neglect of the kids, she may get all defensive and stop you seeing them completely and then what happens to them?
I really feel for you.
I think on balance I would be emailing the kids’ school, explain why you’re reluctant to report to social services yourself bht didn’t want to leave it altogethet. let them do the official referring to social services. But it would be on the understanding that it could cause mean that you are asked to have the kids full time.
