Part of a recent IM...

R: ok..I'll just type my thoughts and you can catch up
R: On one hand, it's not one person's right to tell another person who they can and can't be friends with...
R: but on the other hand, when two people love each other, they should be willing to 'forsake all others'
R: If an outside person's attention or the attention of one of the commited couple pays more interest than just friendship, that takes away from the couple.
R: and you are right, D's friendship is less important that L's love
R: I'm sad for D but if she is a true friend, she will understand
R: Best case scenerio would be for you and D to be friends and L comfortable with that....but not an easy place to get to
