I think if you break up with him and then one day date someone else you will be grieving TWO loves, and the third won’t deserve that LOL.
Women seem to not want to date again until they are “Ready”. Dear, we would never be “Ready”! You will always keep the last love fresh in your heart. Maybe not date anyone the moment you break up, but don’t be actively single a year later, either! Every day it will get easier and easier to get over the last one. Just have a good time with the new guy when you’re with him!
