Cogito 's description sums it up perfectly. It is, beginning-middle-and end, a world class mindfuck. It is orchestrated and sustained by choice. He could just as easily choose to compliment your hair, your bravery, and the bright future your baby will have, yes?
Imho, (and experience), the foundation is based on control. As a mom (and this applies even before the birth), your attention will rightly be on your baby. From what you have posted, crazyoldlife, he seems to be doing/saying anything to keep your attention on him. This is who he is and from the severity of abuse he is dealing out to you, I would not be betting (or even hoping) that he could/would change...in the sense of evolving into a mature responsible adult. Imho, this pattern of behavior may be determined by his personality type, which, (again, just my opinion) will not change.
Crazyoldlife, he is shaming you (from your Tues-01:52:05 post). The future of your mental health, as well as just about every aspect of your baby's life is at stake here. You have nothing to be ashamed of...AND you can choose how much shame you feel...that is not for someone else to assign to you. Same for guilt.
Please trust the advice on setting the necessary boundaries for essential communication regarding his child...and promptly ending any communication session that strays off the topic of the baby.
Congratulations on your pregnancy!
