Thank you for your letter. My experience with men who are chronically jealous, as well as what some of the literature suggests, is that these are traits that tend to be very consistent, and often get worse. That is why I am recommending you have counseling before the baby arrives. His behavior will create more and more resentment with you as time goes on. Ultimately you’ll feel even more unable to “get it right.” For this I highly recommend couples counseling. The find help tab at the top of the page will help you locate someone nearby.
You are now in orbit around his jealousy and that orbit will tighten as time goes on. This is something you need to address sooner rather than later. If he won’t go to counseling with you, it would be important to go for yourself.
