I have to agree, there are red flags here. That is a pretty immature thing for a 32-year-old man to say to his wife, ESPECIALLY being in a calm voice,and YOU should not have to move out if he is bored. Marriage is not all fun fun fun and boredom is natural at some point if you are married long enough, you work on the marriage, you change things up, you don't just tell the other person to LEAVE with the kids.
And if I were you, I would not GO, you are establishing your residence and the place your kids will live. Make sure you set them up in the best house. This could be the prelude to being "left." I would assume so if that were happening to me.
Being the way you are is an asset, don't let him make you feel hokey or inadequate. You are not being appreciated. He would rather you WASTE money? In this economy? This all sounds extremely immature, and actually, like a lie told by a man motivated by something else. I don't know your hubby, but don't let the shock of this allow him to push you around. Get a real strong backbone. You need it for your kids right now,if not yourself. Say fine, you are bored, go do your thing, but you had better be ready to send most of your money supporting the kids cuz you are gonna make sure he doesn't take his new, higher income and not share it with his children, that you won't let him be that utterly selfish. He married you for better or worse, now things have gotten BETTER and he wants to leave? He needs to man up.
Personally I'd be questioning if this is a man you really WANT. If this is how he behaves when things are good, what will happen when the chips are down? To tell you the truth, I would suspect he is having an affair, or wants to have one and at least isn't cheating, getting rid of you all first. How kind. Boredom is not enough reason to tell your family to leave. And I really cannot imagine what my reaction to this would be. Certainly to love him a little less. Bored with his kids? At 32? Shame on him. I'd be reevaluating my feelings towards this man right now if I were you, and finding a good lawyer to protect yourself. At the very least, do not allow him to treat you this way. Demand more of him.
I only know a very small piece of your story overall, so I could be waaaaay offbase, but be careful! I ran this story by my hubby, his remark was "Get as much cash as you can from your accounts and get a lawyer tomorrow."
