PLZ HELP!!!should i or should i not?!?!?!?!?!?! ?

My birthday is tomorrow but im celebrating it this tuesday. Ok... so im turning 14 and im probably just going to have some time to hang out a home with my friends and well have some cake. Ok so my dilema is im thinking about inviting my boyfriend and his twin brother( he is also ky best friend) we have been dating for 2 years so ya but my boyfriends brother was dating my best friend (she is a girl) but they broke up last year in june they talk once in a while i mean its not like their enemies or stuff but i was thinking that if i invite her well it might revive some memmories and stuff( she was the one that broke up with him he was really sad at first but well he is over it, she is currently dating someone now) so thing is since she is ky best friend i want to share my day with her but he is also my best friend so i dont want to produce pain in him. So should i invite my boyfriend, his brother and my best friend????
