In addition to this, I just want to add a few things.
I needed time to process what happened. I ignored some red flags and paid the price. I needed to reevaluate that decision making process.
It helps to get back into a groove, especially with kids and a schedule. Develop a daily/weekly routine and adjust to a new life.
Explore new interests on my own. Memories are made by experiences, both good and bad. I needed some good new ones that were just me (and with my son for some, too).
Finally, time off helps you be OK with being alone - you aren't looking for validation via a partner.
