I agree with Cadence. And also want to comment on something from your earlier post- about whether you should even answer his texts about when he's coming home, etc. Although I understand you logic behind saying, I've got it under control, no need to come by, etc., I think if I were you I'd ignore every single text and not answer unless the house was on fire. HOWEVER, I'd have a little spiral notebook in my pocket at all times, and record every time he does it, what time of night it is, kids already asleep, he came in, said nothing to anyone, showered, got on couch. Say nothing to him. Nothing. You're not DBing to save the marriage any more. You're a Mama Tiger who is protecting her future and that of her babies. Document, document, document, but without any interaction with him. Don't give him that space in your life or your head.
