Should I end this friendship?

I need an outside perspective. I’m currently on a two week trip with two friends. One of them (Friend A) invited me, and I suggested offering the invite to our other two friends. I was already hesitant because a previous trip with this group was rough due to Friend A and Friend B having a very clique-y dynamic where they exclude others and mostly focus on each other.

Unfortunately, it’s happening again. Friend A and B mainly talk to each other, and I often feel ignored. I’ll make a comment and get no response, but when Friend B says something, Friend A immediately engages. Friend A purposely ignores me and it feels like I’m tagging along on their trip rather than traveling as a group, which is confusing because friend A wanted to travel with me. It’s also extremely immature for 31/32 year olds. Just blows my mind people even behave in this manner at this age.

What’s making it worse is that I recently ruptured my ACL after we booked the trip. I did two months of PT and got to the point where I could walk again (I was going to cancel if I couldn’t walk normally). I let them know before the trip about the injury and that I can walk again, they assured me we’d take things slowly, but once we got here, Friend A constantly walks far ahead without checking on me purposely, and Friend B follows her. I use a cane and physically can’t keep up. There have also been times when Friend A watched me struggle with my suitcase and didn’t even offer to help. Friend B at least sometimes offers. But it’s so strange, you’d think a true friend would be concerned to make sure I’m ok as this was a bad injury, not a small one. I understand that no one is obligated to cater to me because I’m injured, but I would have expected a close friend to show a little more awareness and consideration, especially after assuring me beforehand that my injury wouldn’t be an issue.

I’m trying to figure out whether I’m overreacting because I’m frustrated and hurt, or whether this is a legitimate sign that I should significantly distance myself from this friendship or end it when I get home. What would you think in my situation?

We are college friends and see each other in our 4 friends group (all girls) maybe 2-3 times a year, so don’t talk often.

Feel free to ask any questions that might help provide additional context.
