So I (45M) have two biological children (20F and 18M) from my first marriage, and two stepchildren (16F and 14M) from my wife’s (39F) previous relationship. I’ve been married to my current wife for 10 years. Their biological father is still involved in their lives and pays child support.

Recently, I updated my will and left the majority of my estate—my house, savings, and investments—to my bio kids. I set aside a small amount for my stepkids (about 10% split between them), but the bulk is going to the kids I raised from birth.

My wife found out and was furious. She said I was “punishing” her kids for not being biologically mine and that I’ve been in their lives since they were little. I told her I love them, but they also have a dad who will leave them things too, and it doesn’t feel right to split everything evenly when I worked for most of my life before they even came into it.

My bio kids are also upset—they feel like they’ll have to “share” what would’ve been theirs if I stay married to my current wife, because of things like the house being sold or used jointly. My stepkids don’t know yet, but I can already tell it’s going to be a fight if they find out.

AITA for not giving my stepkids an equal inheritance?
