WIBTA if I leave my husband while pregnant and move across the world?

UPDATE: I booked a trip to visit my sibling for a couple of weeks so I can have some space to think about next steps.

Thank you everyone for responding. I’m going to read all of the replies a few times so that everything sinks in. I really thought it was going to be split with people telling me I’m wrong to take his kid away. It’s hard for me to see the danger when it doesn’t feel urgent and things are good most of the time.

Update 2: I got some bad news that the baby might have some medical issues. I have to cancel my trip while I’m waiting to see a genetic counsellor and for additional tests. I will not be going anywhere for a while but my husband has been very supportive.
