should i have the right to be upset?

My man and I spent 2 full days together but, the last day was just full of family drama (his family towards each other) I didn't have the time I wanted to spend with him because of them. My So is leaving on Thursday to spend 3 weeks with them and I couldn't go he told me since it was so expensive "last min". I just feel like he spends more time talking to them than me... I don't know if it's pregnancy hormones or not..
