Middle Name Regret

I need some advice...I will start by saying that I love my dad and am very close with him. He’s been an amazing father and has always been there for me my whole life. Early on in my pregnancy, he generally asked what we were thinking about in regards to my son’s middle name. I told him I wanted it to be after him (bc I did) and he was surprised and honored. I thought it would be a great way to honor him after everything he’s done for me. As time went on and delivery day came, I started realizing that this could be the only boy we ever have, and I wanted to name his middle name after my husband who I love more than anything. I ended up choosing my dad’s name bc we already talked about it and I didn’t want to hurt his feelings even though I really wanted it to be after my husband. My son is 4 months old and I’m still wishing I picked my husband’s name to be his middle name. I can’t shake this and think about it every day. I’m not sure how to just move on. I’m just upset at myself for saying anything at all because I’m the one that put myself in this position, but I just love my husband so much too and feel like my son should have his name bc he’s his son.
