Hey there Jordan,
I'm sorry about your parents divorcing. It must be rather difficult for you.
But this could be for the best. Instead of having two people in a marriage that does not make them happy, they're both free and on their own. Your mother, no matter if she does or does not have feelings for anyone else, would not be happy in a marriage with someone who does not love her.
You also need to remember that this does not have any indication on the love that your parents have for you. They both love you, and even if you are moving away, you will still see your dad and be able to spend time with him if you want to.
Feel free to message me if you would like to talk
Kyra
