Some suggestions, not all of which need to be taken seriously.
Use obvious questions: “What would you like to ask me about my day?”
Use interaction: “I’ve got a problem at work and I wonder if you could give me some thoughts on how to deal with it.”
Use novelty: Make sure that you don’t talk about the same aspect of work twice.
Use silence: Stop talking about your work until he asks about it; “……………………….”.
Use humour: “I see that your eyes have glazed over again. It’s lucky that I work for a window replacement company”.
Use sex: “I think that once you have asked me a question about my workday we should go to bed where you can discuss my CV in considerable detail.”
Use superhuman strength: throw things around the house and garden until he asks in a timid tone “And how was your day?”.
Use shock: Write on the bathroom mirror, “PAY ATTENTION TO ME!”
Try inserting some imaginative stuff into your daily discourse: “Of course, it was the astronaut in the wastepaper bin that really caused the problem with the photcopier.”
Try training him: Every time you come home and he doesn’t ask a question about your day you squirt him with a water pistol. After a while he’ll make the connection.
Try talking to him: “I would really like you to occasionally ask a question about my work because I’d love you to be interested in what I do, and I want to share details of all the things I do when I’m not with you. It makes me feel close to you.”
Take him to work with you. Then you don’t have to talk about what happened during the day because he will have been with you all the time. Or alternatively, meet at lunchtimes so that you feel the connection during working hours.
Find lots of joint interests. Make sure that you and him do lots of things together outside work that you can talk about them to your heart’s content, and you don’t feel the need to talk about work.
Try more two or more of the above suggestions simultaneously. It will be guaranteed to get a response.
On a more serious level you are right to be concerned/upset. I think that in many ways marriage is a series of adjustments where we do (or don’t do) things and our spouse lets us know that they are upset with us. This may well be one of the adjustments that your husband needs to make.
