Am i being rude?

My good friend is just separated from his wife right now. Not divorced yet. Hasn't even started the actual divorce process yet. Dragging his feet but thats a different story for a different day.

He lost his job due to covid and has been job hunting all this week. Had 3 interviews. And then proceeded today to tell me about the 3 different places and wanted my opinion on which he should go for (got offers from all of them). He wanted me to help him make a decision.

I nicely but honestly said this really isn't something I cant help you decide. Because this is your life. Not mine. I also said if anyone you ought to ask your wife because this job does affect her too as this job will be supporting her and the children you guys have together. I dont know your needs. I dont know what's best for you and your family. So you shouldn't ask me.

He told me I was rude and hung up the phone because I'm refusing to help him make a decision.

***EDIT***

I didnt want to get into this just because I didnt think it was relevant. But due to some of the comments I just want to add this.....He and I are really good friends and have been for years. Im not sure at what point it changed but basically 10 months ago he announced to the world that he was sick of his wife and had fallen in love with his best friend. Aka ME. I was not privy to this. I had no real warning. Just one night he came to my house unannounced after they had another one of their complicated and messy and violent fights, sat in my drive way and thanked me for always being there for him. Declared that he was leaving her for me.Proceeded to kiss me. I pushed him away. I was caught off guard. The next day he kicked her out said im leaving you and will marry her (ME) someday. He still has it stuck in his head that im the love of his life. He keeps telling me he's going to marry me and spend the rest of my life with you. He put me in a terrible spot. I've been bashed on every platform by her and her friends and family for stealing her man apparently. When all I ever did was befriend and support him. So yes. I've definitely pushed him away because of this chaotic mess. And believe I'm NOT the person to help him make this kind of big decision at this point in our somewhat awkward friendship...where he is obsessed with me and im just trying to keep peace and not get mugged by her friends.
