My (33m) wife (34f) put a member from her gym in her will?

I'll get straight to the point. I opened my wifes (34f) laptop to print out our put together shopping list and in her bookmarks I found her password log for her bank, life insurance and other financial accounts. I checked it all just out of curiosity. She would be leaving behind $100,000 in her life insurance, but 10% of what she leaves behind is for some guy named Caleb, who I didn't know. He's from her gym. I asked her about it and she told me it's true. She met him at the gym, they're close friends, they went out for dinner sometimes and she wanted to leave him a little something behind in case she passed away (she has cancer, stage 3, it hasn't really affected her that much yet, aside from losing some hair). Now I'm not really the type of guy to be jealous over nothing, but something about this just doesn't feel right. I know she's an adult and can do what she wants but I feel like leaving someone in her will (other than me and our kids) is disrespectful towards me. I mean, what's she going to do next, leave the house to her? I told her to take him out of her will and she refused and told me that it's her decision, I don't have any choice in it. Now I feel like we're having a war over a dead woman's money. I feel disgusting even thinking about this but it's concerning me. What would be the best way to approach this? I really don't want to be fighting over this and I want her to feel comfortable knowing she can give a little money to her friend but I also want to feel comfortable in my marriage.<br><br>&#x200B;<br><br>tldr: My wife put a man in her will. Feel disrespectful towards me. How to approach this without a fight.
