Just hormones?? Or really messed up?😕☹️

My fiancés bday was yesterday and I had a nice surprise waiting for him when he got home that he wasn't even expecting.. Soo fast forward to today.. He got up early and got his hair cut by his best friend and when he got home, he explained to me while I was washing dishes and making breakfast, that he was going to the bar today with his friends and would be home early to celebrate New Years with me.. I was trying to hide how hurt I was and I told him to just go and have fun.. But I never go anywhere but work and home, unless it's once in a blue moon when we go see "his" friends.. I sit  at home every weekend and it's been this way before I was even 20wks pregnant..😕Then he says he's just gonna stay home like I'm ruining his night and I need his pitty attention or something..  Im only upset because he didn't even ask me if I wanted to go out or have diner and I'm the one who can't even drink as it is and is carrying his twins trying to stay healthy in the house.. Am I being a bitch or would anyone else feel some type of way about it..
