Feeling hurt

Might be my hormones, might me my emotions but I just need someone to say it I guess.

So my husband git this out of town job, we have been waiting for a confirmation start date so we can book his flight. We have a joint account. He got a confirmation and booked his flight even before talking to me. It has really hurt my feeling and u am trying not to cry. I was expecting some kind of communication before he started booking flights.

Could I be over reacting ? I just had a baby 10 days ago and I have an 18 months old toddler. Where do I start? He barely communicates with me and with my last pregnancy the first few months he was chatting with other ladies cause he couldn't deal with my emotions.

I am lost right now, I know we need the money we owe over $100k and he wants to pay it all asap.

Advice me please
