agree with all you said, i know R&R are often represents as THE couple of Friends but for me it's mondler, i mean when you really think about, they were only a couple for what ? like a year (2nd half of s2/1st half of s3), they spent more time seperated than together
whereas mondler have been together for 5 YEARS, we saw the friends/lovers transition, we saw them fight and make up and try to work things out, they got married, they actually faced problems but deal with TOGETHER
