Congratulations, Puppy, on your baptism! It looked really lovely
I'm not religious but would consider the name Grace for a girl. Don't count DH out just yet!
Heart, I am sorry to hear about your struggles. I think you are doing exactly the right thing by following your heart and pursuing your career as a therapist! As others have mentioned, it is a normal thing for caring men to worry about finances when fatherhood dawns on them.
We know a couple where three days after having a positive pregnancy test the husband went out and bought a house!

Even my husband who pursued a career for personal fulfillment rather than money (he prefers to work in the public sector) and supported me in going part time when I struggled with the losses keeps bringing up that he expects me to continue my career and become the main earner (we earned the same until now) once ducky is a year old. Hmmmm. I'm not sure I'm looking forward to the stress and long hours I used to have. I'm thinking of changing careers and going freelance!

Even though I know it will be paid less with no career progression it will hopefully fit around kids better.
In essence, heart, I think your DH is just having a little panic as he realises that his life is about to change dramatically. He can't complain about the arrival of the baby directly so this is how he is letting his frustration out. As hard as it is, try to stand your ground and wait until the panic subsides. Once your baby arrives and reality hits I'm sure he'll be besotted and his attitude will change yet again.
