i think you have one thing right, if you let the one you love go, and if they return...they love you back. And maybe in his case, he will miss what he doesnt have now, which would be you. All i can say, is that you need to focus on you and your son right now. It isnt gonna get you anywhere to dwell on it. And nothing you say or do is gonna make him change his mind. Give him his space for now, and move on. If you need to talk to me just message me anytime. I am on here atleast once a day.
