Imagine what people would say if the genders were reversed. “AITA for cutting out my daughter for not wanting to raise a child”

I am a father to 3 “young adult” (ages 18, 22 and 24) sons who live with me and who for the most part have always gotten along (normal brotherly fights but nothing serious). However throughout this summer I’ve noticed a bit of a tension between them. I told my youngest to spill the beans since I figured the conflict was between the older two since they seemed the most tense. My youngest tired to avoid eye contact and kept trying to play dumb but I kept pushing. My eldest child had some bad history of impulsive behavior when he was a few years younger (the worst being an incident which resulted in his expulsion from college) but he had been slowly improving his life and I didn’t want to be too late to help him if he had done something to jeopardize itI really didn’t want my youngest keeping secrets.

When I finally got the truth out I was in shock, it turns out that middle child gathered a baby (my granddaughter) over a year ago, but had refused to even see the child. My oldest found out since he happens to work with a cousin of the mother, and he has been trying to get his brother to take responsibility and be there for his child, but he has refused.

I confronted my middle child and we got into a huge fight. He claimed that being a father would ruin his plans for life but I told him that he had to take responsibility for his own actions and that his child deserved to have a father in her life.

This went on for a while when I told him that if he didn’t think his own child deserved a father then he didn’t deserve a father himself and I told him that he had to leave the house. He is 22 years old and has a decent job and plenty of friends so I wasn’t too worried about him.

I have met my granddaughter and her family and have made some plans to sell my house and downsize to begin a college fund for her since my youngest child will go to college and my oldest has been saving up to move out.

It has been about a month now and while I feel like I made the correct decision, I still feel terrible. I chose to end my relationship with my son, which hurts so much, since I have always felt closest with him throughout his life (he had the same interests that I had and was the most willing to spend time with me) I feel horrible that I raised a kid who was willing to not care about a human he helped create, I feel like i ruined any chance of a relationship between him and my youngest son, and I feel guilty since my wife has been crying a lot the last few weeks and I don’t know how to fix anything.

AITA for this? Was my reaction too strong?

Edit: He is also incredibly lackluster at paying his child support, he has to be told to do it and even then he is reluctant.

Edit 2: a lot of people are getting upset about my reaction to the youngest child, however my oldest and youngest both have been trying to get him to own up on his own for months before I found out

Edit 3: also I have seen my granddaughter more than once, selling my house is not a knee jerk reaction since I we have been think about it for over a month and still haven’t made ANYTHING official (and my wife and I came up with this idea together )
