Sal, I’m glad you had a productive work day. I agree that gathering your gumption and being proactive at work can also strengthen your personal resolve and invigorate your fierceness.
You are a fabulous, loving woman who has given your absolute all to your marriage, family and work. You gave this man a beautiful life, but, as you said, he made a mockery of everything.
You were smart to keep your distance yesterday. Shut down all but chats about the children. His gushing about OW was beyond the pale. He obviously wanted to cut you to the quick as punishment for sending him away. Don’t give him further opportunities to bludgeon you.
Your eldest will eventually adjust, but his (I think you said ‘he’ earlier) distress must be gutting for you. You were wise to encourage H to see the children frequently now and then taper to a structured schedule. A schedule and stable routine will help your son know what to expect, which can provide a sense of control for him. Your youngest would also benefit from the above plan, if he/she feels confused. (Can you share their approximate ages?) As for telling your son that daddy will be living in a new house, you will know what to say and when to say it, because you know and love your boy. Will H’s new place accommodate visits from the children?
Sal, you’ve had to endure blow after blow, but you’re getting stronger and you will prevail.
