Bf problem

Ok so i’ve been dating my boyfriend for a year now. I’m in my last semester of nursing school. I was in clinical today when I got a text from him out of nowhere saying that he applied to this job down south which is about twenty hours (driving) away. He said the pay is amazing and he’s super qualified for it. He wanted my opinion. I told him i’m happy for him and that i’m glad he applied!! I support him and his decisions. However, i’m just starting my career. I barely have money saved up. It would prob be easy to get a nursing job down there but i’ve never lived away from my family. I think i’d be extremely stressed out being in a new city just while starting my forever career. He asked if i’d consider looking for jobs there, but I really think i’d be so difficult for me. While I am happy for him, I do feel kinda sad. I have a lot of relationship anxiety, and I feel like long distance would just make it worse. I’m not sure what to do. I don’t want to show him my sadness, bc I don’t want him to have to chose between me and a job. Or I don’t want my emotions controlling his decision. so I’m trying to hide them. Does anyone have any advice :/ :/
