I agree.He is not what I would consider a best friend to do this to you. If your boyfriend was a real man he would not go to the wedding. His choice will let you know who he feels is more important in his life, letting his friend treat you like crap and him being OK with it or standing up for you. It is not like he has been going out with you for a week.....you are a couple. What he does in response to this will tell you a lot of how he feels for you.
