You are divorced now; the state has sent you documents proving you are now a free man or woman. There is no perfect amount of time that you must avoid dating. Some people are able to handle dating few months after a divorce while it takes many other years to be ready.
Experts suggest that you wait for about a year before you date someone. It takes 365 days of being single, going through important days like your birthday, holidays and everything else on your own before you can truly fall back to loving yourself.
Do not rush into dating; don’t use it as a distraction for your loneliness, boredom or insecurities. This will only cause more problems for you and the person you are bringing into the relationship.
So take some time to heal, love yourself again, treat yourself well and be sure you are ready to date someone before you do.
I would certainly let the dust settle for a couple of months. Divorce is a very negative experience and some seek to restore their confidence immediately by entering into one or more relationships - as though to evidence that someone finds you desirable.
This is a mistake unless a casual hook-up is all you and the date are seeking. A new relationship is more likely to be successful if you can learn from your failed marriage. What went wrong, and can you avoid a repetition? Many people find they end up with the same problems in a second or third serious relationship. Don't let that be you.
Meet people of both genders in group situations and socialise as happily as you can, preferably with the focus upon some activity such as sport, theatre or interest base. That takes the heat off friendships and if you find someone in the group you want to date, at least you will have seen how they interact with others first.
