UPDATE: Me [37 M] with my wife [32 F] who wants to name our son after her deceased ex-boyfriend.

First, thanks for everyone who responded to the thread:

I talked to her about the name and she did affirm that it was the name of her ex boyfriend. She apologized for not making it clear to me before.

She and I attended different universities, both in different continents. So we had very little contact during that time, thirteen years ago. She did tell me about her ex's death a few months after, when she came to visit me. All she said then was that he passed away from an accident. She didn't go into detail or anything. I should have remembered, but that was long ago and so much has happened in my life since then.

Today, I asked her if it was okay for her to tell me what happened in detail. She agreed, and told me about how she was sitting on the bleachers and watching the football game when he was suddenly hit in the head, giving him a concussion and almost instant brain death. She told me about how she ran down to the field and tried to give him CPR. Honestly, I almost regret making her go through that painful memory. I could not imagine the pain and horror she was in at the time, watching her boyfriend die in front of her. She rode in the ambulance with him, and stayed with him in the hospital until he was officially pronounced dead.

The university tried to get her to see a psychiatrist afterwards, but she declined, because she didn't want to be seen as "weak". She said that afterwards, she tried to pretend that he never existed. It was her way of coping, however unhealthy it was.

She told me that she wanted to name our son after him because he was a wonderful guy, and she was tired of pretending that he never existed. According to her, they were really good friends before dating, and she told me that he was probably the kindest, most genuine, and most compassionate person she ever knew. He was her first friend in university, and they had a lot of great memories together. She said that he had the heart of an angel, and everybody loved him and respected him.

So yeah, we're going to give him the name. He wasn't just her boyfriend, but one of her closest friends during university. And I think it's a good way of paying respects to a great man who died too soon.

TL;DR: Talked to wife about her ex-boyfriend, agreed in the end to name our son after him.
