After being married for 18 years and now divorced-amicably, is it ok to have feelings or is it time to forget?

just wondering how long you have been divorced?that is rather important, but either way its important to understand why the relationship ended, really try to understand why it ended, then you can put your feelings to rest,take your time get to know and like being with yourself,then you will be ready to let someone else into your life .don't just replace the void in your life with the first person to come along.and if all that fails to enable you to take the next step in your life you will need to do some soul searching,and broach the subject,,,, did i make a mistake?? can we reconcile?tough question maybe tougher answers wish you the peace we all deserve
