When is okay to start dating again after a failed marriage? My husband and I have been seperated 6 weeks.

We have been separated for almost 6 weeks (as he is in jail for D felony assult & D felony intimidation). I have filed for divorce because there is no way to patch up the failed marriage. So when is okay to start dating again? I have 2 children and my #1 job is to be there for my children. But I also have to look out for my own happiness as well. Any advise, please?
