B, I'm sorry. Learning that your H has taken that step is scary and hurtful. I remember when my H took the same action. He wanted a fair (no such thing with an MLCer), cheap and quick divorce and he wanted us to use some fly-by-night mediation service. He completed the paperwork and dropped it off for my signature. I refused. I knew at that point that all of his actions going forward would be self-serving and I was right. I know mediation can work and is a lot less expensive, but both spouses need to be amicable and in the right spirit.Your H is moving really fast. Mine did the same.
It is amazing to me how many people will leave a marriage, knowing they will hurt their kids and create financial strain on both households. I believe most marriages are salvageable with commitment and hard work. It must be incredibly rewarding for those who chose to weather difficult times together. On the other hand, dumping your family to seek happiness with OP seems empty and shallow. I'll never understand it.
Remember, you don't know what the future holds. Just because the process is started doesn't mean that a divorce will be finalized. Take it a day at a time.
