I just know that as I sit here and write this many many people are going to disagree but however I am going to write it anyway. After recently watching the proposal eposoide and how Richard tries to win Monica back it occurs to me that this situation is very similar to the present love triangle.
I know that it was two different situations and different people, but when Richard came back to Monica raving about how much he loved her and it was obvious she wasn't totally ditching his offer I don't think many people were thinking "go for it Richard" whilst Chandler was running around trying to locate Monica to propose. Monica seemed to be upset that Richard was pulling all this on her; when in fact he should have been pulling it when he had his chance. When they were together...
Monica: Oh God� (Starts looking around.) Why don't they put chairs back here?!
Richard: I know this is crazy but am I too late?
Monica: What the� Yes you're too late! Where was all this three years ago?!
or when she is upset over the fact that Richard didn't relize this when they were together
Monica: Fair? Please don't even talk to me about fair! Fair would've been you wanting to marry me back then! Or fair would've been Chandler wanting to marry me now! Believe me, nothing about this is fair! Nothing! Nothing! Nothing! Nothing! Nothing! Nothing! Nothing! Nothing
Now exactly with Richard who had his chance and lost it it is the same with Ross. The fact of the matter is if he really loved Rachel he would have discovered it about 5 years ago and asked her to marry him. He was waiting on her forever and if he really and truly loved her he would have married her before she got away.
With Joey he is the one who is now in love with Rachel. The one who proposed when he found out she was pregnant just so she wouldn't be alone. He is the one who didn't wait a whole season and hide in the corner. He told her about his feelings and just because she didn't reciporate them at the time doesn't mean she won't. After all she said "yes" to his "proposal"
Yes I know these are two very very different situations and they really are different, but I think there are similarities in the two situations. With Ross and Joey both being main characters that were are attached to; it makes it difficult to chose a side.
