<human>: The past couple months my recent boyfriend has been talking "up" my birthday a good amount. He has continuously told me how much he loves to celebrate his loved ones birthdays in a big way and mine would be no different. 

Suddenly a week or so ago he has decided to go out of town on my birthday. I was upset by the fact that he spent so much time telling me how he could not wait to spend the day with me. I do not care about gifts or material things, just the time spent together. He knows I have spent every birthday alone and I was really looking forward to the memory of having it together. I am hurt because it seems as though he does not care enough or respect me enough to keep his word. When I told him I was upset about this his only reaction was "mhmm that is your birthday." He then immediately changed the subject and started talking about the details of his trip.

Also, as of yesterday he decided to extend his trip by two weeks so he will be gone the entire month. I am worried this is a sign of future lack of respect in the relationship. Any advice is appreciated!

Can you give me the gist of the text in a nutshell?
<bot>: Boyfriend made birthday plans for me months ahead of my birthday, bailed a few weeks before to go out of town.
