<human>: Around Jan 2015, my interest group came up with the idea of holidaying in Japan in December. There however, was not much discussion until now. I've been totally excluded from the prep work.

My ex and I broke up 5 months ago and ended things on a sour note, which could explain why he chose to exclude me. When I went to others in charge of the trip, they eventually kept redirecting me back to my ex, claiming that the accommodation was full and flights were already emailed to the agent to be booked. Hence I have to go through my ex (who is the chief planner) to get through this trip as I'm very eager to get to know others in the group well.

It doesn't feel fair as I've been awaiting news on this trip for months. Reddit, how should I handle this issue?

Can you provide a brief overview of the text?
<bot>: ex excluded me from trip that i was already supposed to be in. Really really eager to go but has to go through ex. Not on talking terms hence not sure how to approach ex on this subject.
