I've thought for awhile that it sounded like you really needed a good, solid break from Pea, time truly to yourself. Among other things, it sounds like this will start providing that for you, when Pea is with his father. As someone else said, it will probably also be good for their relationship with each other.

You might feel some grief later, but you might not. It really sounds like this was the best, healthiest decision for you.
