AI, please...you're pregnant. If he's going to fault you for not cleaning the house while...what, 6 months pregnant at the time this started to be an issue? That, to me, shows a blatant lack of care or compassion.

EVERYONE does wrong in ANY relationship at some point or another. It's an inevitability. Couples are going to bicker and argue from time to time. It is NEVER a seamless process of melding two lives into one. Never. The key is withstanding those petty disagreements and remembering why you loved him/her in the first place. HE failed that test, NOT you. To be perfectly, 110% honest, I don't think cleaning had a darn thing to do with this.

You have done absolutely nothing wrong, AI. Your little girl is going to be lucky to have a mom like you. I have no question about that.
