I, You've been given wonderful advice. Do not call him unless it's an absolute emergency about the children. You will now need to learn how to handle the day-to-day activities on your own. Yes, you are now in the roles of both parents.
Your h is in what they call the honeymoon stage or euphoric stage. It's going to take a while for the both of them to realize that the day-to-day routine is going to over take them in this stage. Right now, it's peaches and cream with a cherry on top. Settling in and actually being responsible people will take a while, but they both will come to realize that the fantasy can't last forever. Time is on your side in this area.
So, while they are playing house, you will need to keep the focus on you and your children. Start making some plans for the holidays, i.e., create new memories, make new traditions and just leave the runaway child out on the street. He'll be just fine.
Eventually, your "child" will become curious as to why "mom" hasn't called or made attempts to contact him or have him come over. When he does start sniffing around, do not tell him what you've been up to. Keep the focus on the children. He's going to need to learn that you are a wonderful person who has a lot to offer. He gave up the right to know what you are doing when he walked out the door.
He will try to push your buttons, don't take the bait. He will play the pity party as well...don't fall for it. Keep an eye on your assets at all times.
It's a long, hard road, but you will survive and become wiser along the way. You must might be surprised at what you can do on your own. I know he will be surprised when he does peek out again.
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.
