You can date at anytime. However, if your kids are young, protect your kids until you are certain you have a real relationship. Wait to get into a real relationship until you are ready. If your kids are older, be open with them about your relationship decisions. It will make them healthier adults.
15 days for each kid you have + (.2 x AGE)
depends on how much you think you might get back with the person
all that need time because of love stuff doesnt really matter if youre suppose to move on
so immediately if you feel like it
6 months....... give every one time to adjust
I don´t think it is a matter of how soon but who you should date.
