Melody, please don't think you're a burden.
All you were being is being the girlfriend of your boyfriend, that's it. It was HIS friend's fault for being disrespectful to you and your boyfriend, HE was the one that was making the moves on you, HE was the one with the retarded laugh, HE was the one putting the friendship between him and your boyfriend at risk when he started putting advances on you. If anyone's a burden, it would be HIM being a burden to your boyfriend, because you just don't start hitting on your best friend's partner.
I hope this post helps you realize that you're not in the wrong for telling your boyfriend.
