I 21F and my boyfriend 21M just had our first child a son in October of 2024. We will call him S and my boyfriend J for privacy reasons. J and I have recently been discussing who we would want to be the legal guardian of S if we pass. Neither of us want it to be family due to past trauma from both sides. J and I both decided on my childhood best friend H who I’ve stayed in contact with over the years and still meet up with all the time. For background H and I and her twin sister K have been best friends since we were 12. K’s son even knows me as auntie and the same for H’s daughter and they are aunts to my son as well. So J and I picked H as a preneed guardian which is essentially the legal version of a godparent. Now I have another friend we will call her M. M and I met in a mental lockdown facility when I was 16 and she was 17. I was put in there due to my mother essentially abandoning me. When we both were released we reconnected and I found out that M had a baby. Fast forward to current day and M has only met my son once and we have only met up to do things together twice. When I told M about the conversation J and I had and how I asked H to be my son’s preneed guardian and how H had agreed M proceeded to blow up on me saying she can’t believe I would not ask her and I’d ask someone else when I tried to explain that H was the best choice considering H and her sister K are the only childhood friends who have never backstabbed me even once we’ve never had major problems and I’ve never had to cut them off for any reason. Plus if anything were to happen to J and I, I know that H has connections to both families considering J, H and K and I grew up in the same town and would make sure each side of the family would get equal time to have supervised grandparent visits and would know the type of stunts our family pulls. I even had J proof read my responses to make sure they didn’t come off wrong or harsh but M wouldn’t hear any of it and insisted that I had slighted her and upset her and stated she couldn’t understand why I wouldn’t choose her. And now she is barely speaking to me so I’d like an outside opinion so AITAH?
