If you're not completely free of your marriage emotionally I would not date. You have to consider the feelings of the people you will be dating as well. They're not trinkets to be toyed with. They're human beings with emotions as well.
There's nothing wrong with going out to parties, dances, bars etc. to mingle and have a good time. It's good for the soul. I would just avoid anything that has potential to lead to something until you know where you're headed.
