maybe I'm just too moody

maybe I'm wrong but I got extremely pissed at my DF because we are going to his parents house today to let our LO and SD open their gifts. DF went and got my SD and she opened up her gift already way before me and LO could even wake up. I went off and just told him how rude it was because we're suppose to be a family and it's not fair to LO or me because I wanted to see her face when she opened up her gift and I also wanted the two to open their gifts together! This pregnancy has turn me into a really emotional b**** lol I'm just venting but how can I get him to understand how I'm feeling he feels as if I'm bored and just want to fight
