I'm not going to buy my best friend a wedding present
Why do you not want to buy your friend a wedding present?
I feel like I am lame and a brat. He never considered how I felt about him getting married.
If you are going to a wedding it's expected that you would bring a present with you. You shouldn't upset that you weren't taken into account for someone elses relationship.
Well I am not that upset anymore. They can do whatever they like now.
You should not be bitter over your friend. Have you tried talking to them about how you feel before the wedding. If he is a good friend I think he would want to listen to you even if he won't agree.
