Refuse them both. It won't end nicely but if both follow though and cut both tyes, they really just aren't your friends. It's hard to cut tyes and the only friend has been lost to a extreme lack of communication from not being in the same class and not having the same interests that my other friends all share. Along with that I would like to congrat you on having a relationship for so long with two people who are completely different and unless your friend(s) are really serious, they won't cut tyes with you. I hold long grudges and I only have lost 1 friend from lack of communication. And I have tryed cuting many of my friends off...
