Heartbroken

I had to break up with my fiancé today. We’re expecting a baby but I honestly feel like he’s not the right one for me. I feel like if we’re having a baby and Engaged there’s no way he should still be putting his friends before me. He’s supposed to have been home last night but his friends claim they needed him to stay so that he can help them bring their belongings home since they’re bringing back extra people. I told him that’s not his concern. If they want to bring extra people home they should make room for their belongings. I don’t have any concerns he’s cheating he just can’t seem to say no to his friends. Not to mention he acts a bit arrogant and rude to me when around them. He’s usually so sweet so I just don’t know what to do

I guess I just want opinions of I’m overreacting since I don’t know if my hormones are clouding my judgement.
