I think this forum is just fine, even ifg it's not true MLC, your H's wacky behavior is most similar to some MLCers, so I think you'll find the voices with the most similar experiences here.
Your H, in my eyes, keeps asking for you to stay the course. He's confused but knows he wants his family, doesn't want to divorce right now, wants you to be nicer to him. I think he just got depressed and overwhelmed with work, new baby, and feeling neglected by you as your attention naturally turned to new baby. If you can just calm down, be kind, work on yourself, and wait out your postpartum hormonal issues, I think this can still be resolved.
Granted, you may still decide you don't want to forgive him for abandoning you in your time of need. I can understand that. But your H clearly is NOT well - you might see this as HIS "time of need" as well. Why not just give yourself 3 months to do nothing. Divorce is a pain, full of awful paperwork and stress, even if it's what you want you really don't need that added stress right this second.
