Don't feel stupid. It's been a really short time and what would it say about you if you were able to turn off those loving feelings on a dime? But keep up the focus on building a new better life for yourself, stay busy with friends, and those feelings will fade. And if you want to date, date. I know many will say it's too early, but in a situation like this, a little love affair with someone who treats you right can be healing.
