<human>: Can you provide a brief overview of the text?

A few months ago my boyfriend (two years and living together) said he wanted to organize a big group trip with our friends. He made a Facebook group and added our best buds, and used it to see who wanted to come. The trip is in early 2016.

Last week, he posted the date and resort that he had priced out. He never asked me for availability, but I initially replied that it looked good, and he said that it wasn't set in stone but he wanted to know who was attending by the end of the week.

However, I realized this week that the trip would be in the middle of my university exams. I let him know that those days wouldn't work for me and he said "well the rest of us will just book it and if you can go we will add you last minute".

I said "wait, we can't just move it forward a week or two?"

He replied "I don't want to go on a winter trip in May". Our original date was the last week of April which isn't exacty winter either...

I asked if we could go in March and he said  "no, that doesn't work for [his friends girlfriend]".

I then asked why he would work with her schedule and not mine, and he said "fine, I'll look into the first week in April. Is that okay?" and went on and on like it was a huge inconvenience.

Am I right to be annoyed that his first instinct would be to drop me from the trip? The prices were based on double-occupancy so he couldn't go for a good rate unless we shared a room anyway! It is not news that I'm a student and he apparently checked with everyone else besides me before looking into trips.
<bot>: planning a group trip, boyfriend have everybody a date when I am in school. Wanted to book without me at first until I practically begged to change the date. He acted like it was a huge deal.
