Would you tell your friend if their husband didn't actually want kids ?

I shouldn't say friend but more like good acquaintances. I know a married couple the husband is in his mid 40s wife is mid 30s. The wife has wanted kids for a long time and her husband tells her yes but he wants to wait. He keeps telling her maybe in so many years or whatever. She is excited to be a mom. I was talking with the husband without her one day and he was asking me about being a parent and he told me he wanted the truth not the fluffed up version. I told him it's extremely hard and life is never the same but in my opinion for me it was worth it and it's something I'm happy with. He told me that he doesn't actually want kids and that he's happy with life and taking care of himself and his wife and getting to do whatever he wants, and he told me he keeps pushing the time line but isn't actually planning on having kids. I know for a fact his wife thinks that he does want kids but he's just making her wait. I'm not super close with them but I feel like this is so crushing if I was in her position! I feel like it's not my place to say anything though so idk but I feel guilty knowing this.

What would you do ?
