Should he be jealous of how Im spending my vacation time?

My boyfriend and I have been dating for 3 years now. We've talked about our future, about living together and about marriage, we really love each other. One thing I've noticed lately though, is how he gets jealous/acts possessive and is hypocritical sometimes. One of these instances includes my mother and I potentially going on a mother/daughter trip. We used to do these almost every year when I was growing up, it was a really special tradition we had. My mother is now 80, and she is seeing life differently. She is prioritizing her travel opportunities now, since she won't have access to travel insurance in the near-ish future. My mother brought up the other day that she would love to go see Africa, but she is afraid of traveling alone and asked if I would like to come. I have always wanted to go to Africa! The trip won't be for at least a few years, but I can start saving up. I brought this up with my boyfriend, who has always been supportive of me spending time with my mum, and he became incredibly defensive about it. He said "But, I wanted to go to Africa with you! Why do you have to do these things with your mom. Could I come along?" meanwhile he was recently talking about taking his mother on a trip to Singapore just the two of them (which I was supportive of), and he's going on a trip to India in a couple weeks with one of his friends. He and I both get 2 weeks of vacation time a year, which I would spend most of that (or at least half) on the Africa trip the year we would decide to go. Is he acting possessive? Do I have a right to be bothered by this? How should I respond?
