Boyfriends friend issue

Last night i was waiting at his friends house for hours while they played pool at the bar they come back ans his friend goes off on me saying im to clingy and when we are there in always sitting next to him whispering things and I've been dating him for so long that he shluld know me by now and all this shit... Ive only met the guy like 5 times amd every time he just wants to take my Boyfriend to the bar when im 19 not 21 and complains that he doesnt know me... I'm really hurt by it and Idk what to do my boyfriend said nothing the whole time while i was getting scolded
