Easily replacable man, you need to first pour money, time, and energy into having a healthy pregnancy and a great childbirth experience, since pregnancy and birth are, unlike men, rare. You will probably only have a couple kids. So focus on eating, exercising, being properly hydrated, resting... swimming is an absolute best for the later months of pregnancy.

You need to see a lawyer in regards to possible support from the bf, in the future.?

You need to decide if the bf should watch the birth. It does not sound like his presence at birth would give you any joy, but the decision is yours if he is interested, and, good riddance if he is not interested.

Legal fees and doula fees should take priority over couples therapy fees, in my opinion. First things first.
