gooram, I think you're a bit easily offended!
I think Dale made a fantastic point, and it's something that I've seen again and again amongst extended family and friends (well, friends' parents, mostly
).
It has little or nothing to do with their love for each other, but about the fact that each had developed daily routines that were somewhat independent. A classic example is the wife who doesn't work outside the home, and has developed a full life for herself with art/craft classes, coffee meetings with friends, cards, volunteer work, caring for aged parents, etc. Hubby is busting to retire to spend more time with her, only to discover that he has to make an appointment to see her.
She used to do whatever she wanted during "office hours", without consulting or telling anybody. Once hubby's at home, he - quite reasonably - wants to be kept in the loop, so she has to get used to including somebody else in her daily plans. She'll inevitably occasionally forget to tell him about something, and he'll get annoyed because he was expecting her to be at home... He hasn't yet filled up his week with activities, so it's very easy for him to feel that she has a fuller life than him. Of course, it's a great problem to have - too much time! - and can be resolved, but if you're not prepared for it, it can be a very emotionally challenging time. The high divorce rate amongst couples retiring - and just after the kids have all left home - is testament to this.
It's not about love, it's about logistics.
