Hm is this Normal Between Friends?

See I have 2 really great friends and let’s call one “a”and one “n” (who are both girls like me and unlike me they are very homophobic so before you get the wrong idea no they do not have feelings for me) who are low key very jealous when I bring up one of them to each other in a conversation and I know it’s not because they hate each other And it’s definitely not because they don’t have friends bc they have A lot of friends even more than me and they literally only met 2 times and both of the times I was with them so I know nothing bad happen between them and they don’t even talk over phone but “a” always gets quiet and acts awkward when I bring up “n” in conversations and usually just goes “oh great” or “oh cool” and usually hurries up to bring up her other friends especially her best friend like to make me jealous or something? And same goes for “n” and when I talked to “n” today and randomly brought up a conversation I had with “a” because I thought it was funny said “oh you still talk to her” in a kinda jealous and annoyed Voice ? And some more incidents but I don’t wanna talk about all of it because this is already getting too long but like it is normal between friends or maybe I’m just imagining things and I’m looking too much into things? like i don’t really care but it’s getting kind of annoying not being able to bring up funny things that happened in the conversations I had with one another because it always gets awkward like low key at first I thought it was kinda funny and cute (in a friend way) but now idk
