Marriage advice.

I just want advice and also to know how many married couples would be ok with letting their husband go to a wedding in Dominican Republic(I couldn’t go because I’m to preggo , leaving on Valentine’s Day for 7 days when their wife will be 35 weeks pregnant and have to take care of a 2yo by her self? I’m honestly feeling a way because I’m already a stay at home mom and don’t rlly do much as it is when it comes to my personal life but I’m just confused as to should I be more at myself for not doing much in my life or at him for not being sensitive enough to say he’ll pass because my wife can’t go or what if she gives birth early or being prego & having to take care of a toddler would be too much for her for a whole week!
