I think it's interesting how different people require different things in the same situation. When I get home from work, I am stressed and tightly wound. I need to decompress. This could be eating, slamming things around, or checking my email. BUT it needs to be a solitary activity. My ex would try to smother me with kisses, and I love yous, and how was your days. That has to wait.
Around the same time I was ending things with him, I spent a good deal of time talking on the phone with an old friend. He said something that really struck a cord. How he would greet his now-ex-wife at the door every day when she got home and shower her with his love, but it hadn't been enough. If she was anything like me, perhaps it helped to drive her away.
I have a good friend at work who is clearly of the same make and model as my ex and my old friend. Every morning as soon as I get to work she's trying to chat my ears off. I'm usually running late and highly stressed. I need to get settled, check my email, and take a deep breath after driving in rush hour traffic. I hate shutting my office door because I want to be accessible, but for my own sanity I may have to try that.
