37wks preg husband wants travel

Tara • 02.22.16 ZJLA Baby #2 is on his way!!!!
My husband wants to go to his brothers bday party that's 2 hours away (without traffic). I will be 37weeks+4days pregnant. I told him that it makes me nervous him going so far when im almost due. But he told his brother he wanted to go still. Idk if I'm being paranoid or what. I told him he could come early or late he doesn't know. And he doesn't know how long I will be in labor. What if it's fast and he misses it. The baby has already been head down for a month. I feel like he doesn't even care. Idk. What do you guys think?? 
(I am not going with him. He is going with his brothers).
