Do you think it's reasonable that I'm upset with a friend who didn't get me a present on my 30th birthday?
Probably, did you talk to him about it?
No, I can't depend on him anymore.
I'm sorry that he treated you like that.  Friends should get each other gifts on their birthdays, it's the polite thing to do!  Maybe he just forgot?
If he wanted to give me a present he should have made a big deal out of it and made it memorable.
If nothing else, he should have gotten you something. I would talk to him about it. You'll be able to move past it if you know why he didn't' get you one.
