How to deal with a nearly impossible boyfriend?

So before I even say anything, I don't need people telling me to leave him or people being assholes. I'm not leaving my SO, we have a good relationship and I'm expecting our first baby. We just don't see eye to eye on certain things (like most people). Sometimes, especially cause my hormones are raging, I'm over sensitive and it's hard for him to understand that. I just want him to realize sometimes that my feelings are just plain and simply hurt by his actions or words he uses, but he won't just apologize, he'll continue to argue about it. My question is... How do you ladies deal with someone who has a hard time apologizing, being wrong, etc... I love him, I just need to figure out a better way to deal with him.
