They say people come into our lives for a reason, and it shows a lot that you recognize the good he has brought to your life. It's also beautiful for an ACoA to recognize that someone they dearly love is no longer someone they should have in their life. I'm sure the coming weeks, months, and possibly longer will be hard for you. I wish you all the strength and comfort you can find, and I commend you for being aware of yourself and your needs enough to do what is best for you.
