Rant :(

I feel bad about even ranting about this, and I want complete honest feed back. So my girlfriend works long hours, she’s a manager at a pizza joint. & When she gets off of work, lately it just feels like all she talks about is work. I usually don’t mind hearing about it. I know all the gossip and drama and I’m usually intrigued about everything but lately thats ALL we’ve been talking about every day all day. I told her how I feel about it, that I wish we could talk about different things, and I hurt her feelings. Am I complete asshole? How should I apologize or how can I make her feel better about the situation? Help :-/
