A woman can start dating if she feels ready right after she receives her Get, However she can’t remarry until three FULL Hebrew months have passed. This is Based on the Gemora inorder to know if she gives birth at the end of the 7 month, we would not know if the father was from the 1st or 2nd husband therefore the 3 month waiting period eliminates this doubt.
A man can get married right after he gives the Get to a woman who has never been married or one who was divorced and the above 3 months has passed.
May all of us in this situation no matter what their age, have the faith, courage and strenght to find their real true partner in life.
Anyone who helps in this matter will surely be blessed with Shalom Bais for themselves and children.
