Treese, Just as they hit bottom, so shall we. Once you've bottomed out in your area, you'll rise again and be stronger, more independent and yes, wiser to your situation.
You've stated your opinions/thoughts to him, now, let it go. Continue to move forward and find a way to leave the door ajar, but do not wait on him. Your children need you now more than ever. No one can predict which ones will return and that's why it's so important not to sit around waiting on them.
Yes, you are having a difficult time of this, but you need to understand/realize that you cannot rationalize w/someone who "chooses to be happy" or should I say, sweeps everything under the rug at this time. He's running to avoid everything he's done and he will continue to do so until there's no place left to run.
As for the ow, I wouldn't have been happy either to discover they are out and about w/your son in tow. Again, we just don't have any control over them and what they do. The more you point out the errors of his way, the more he's going to be determined to do it his way. I know you needed to get it off your chest today, but find a way to let it go. He'll never want to be around you if you continue on the rationalizing streak.
Treese, you only have control over yourself and what you do w/your life. You have to take that huge leap of faith and cross over on to the path we are all on. That path will guide you along the way and support you throughout all of it. What's important right now is that you create a stable and safe home for your children. They need to know, and I think they already do, that mom is there for them. You are going to have to get a very thick skin in the weeks to come. Holidays upon holidays are coming up and it's going to get harder to face them if you don't go as dark as you can on this man.
I'm very sorry about the conversation today, but I'm not at all suprised to hear his comments. Typical of that fantasy land euphoria ride he's on.
Take care of yourself.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
