I think for myself a big part of it is also habit. When you are married to someone for such a long time, your ways become habits. It becomes comfortable, it's what you know. Even now, when something happens, I still feel the gut reaction to text him really quick, because we had such a past, and know so much about each other. Now....I do not do that, don't worry! But...I completely get that feeling.
I have not dated anyone, I am just enjoying my freedom right now, and I am super busy. However, I would think if I did date someone it would be really hard to form new habits, or that it would just take time.
Just my .02
I hate that I think deep down most men are big crazy babies. I am going to have to get over that before I go dating anyone that's for sure LOL!
