Don't feel silly! I can so relate!
My son moved back home for a few weeks, after his graduation from college, while he was interviewing for jobs, on my side of the state. ZoE has never "lived" with him, as I got her halfway through his freshman year. But during those 3-4 weeks he was at home, ZoE followed him everywhere, sat on him or next to him, cried when he left the house for anything, laid on the chaise looking out the window at the driveway waiting for his return, and slept with him every single night he was home. I was..like..what the hell???
I have had ZoE since she was 6 weeks old. I'm the only one that takes care of her. she's slept in my bed every night...then he comes home and it's like I don't exist!
My son moved out two weeks ago and started his new job. ZoE moped around for two days...now she's back to normal, And I'm her world again

. Maybe move the hubby out?
