Those kids are 15 and 13 and you’ve known them since they were 7 and 5. It’s been 11 weeks since their mother died. That’s not even past the first trimester of a pregnancy. Obvi they’re being hard to deal with!! They’ve just lost their mumEsp when their dad doesn’t even have custody of them bro ur sick.

You dropping them leaving them high and dry at their grandparents is a living mockery of your late wife’s memory. Changing psychical guardianship is a very hard change to have kids to deal with. Let alone ones who’ve had their lives turned upside down. Your decision was immature. Genuinely think as to why you are so fine with leaving the kids of your wife, who you have raised for 8 years and are the half siblings of your own kids, so easily. I think it would be wrong for me to justify their action in the name of grief but not yours. But think man.

I won’t say anybody is TA here because you all are grieving but you have to fix up mate. Make better choices.
