Please help or just listen

I have a 12 week baby. Been on vacation with her daddy (my husband) and ten year old.

Don’t want to bore with all facts but we had a massive row, I fled when he wasn’t in the room so I could take kids to another hotel for a peaceful night (we didn’t argue in front of kids don’t worry)

Anyway my husband has taken it so bad he now wants a divorce. It’s so extreme.

I’m on a flight right now to London from Miami, husband still there. I’m utterly drained and emotional.

He says he will collect the baby on Thursday and bring her back at weekend. My question, is that right? I would never deny access but she’s so young? And I still mix feed. Omg what’s happening everything was perfect
