Joey is the first to find out.
Las Vegas
[Scene: Central Perk, Chandler, Joey, Phoebe, and Monica are there.]Monica: There's nothing to tell! He's just some guy I work with!
There is actually a plot inconsistently in relation to Chandler first telling Monica he loves her.Technically he first tells her in The One with all the Thanksgivings - Monica puts a turkey on her head and dances to cheer up Chandler and he inadvertently blurts out "You're so great, I love you." He then tries to take this back but Monica heard.Later on in Season 5 in The One Where Everybody Finds OutChandler again tells Monica he loves her for the first time - Phoebe and Rachel know about Chandler and Monica and Phoebe hits on Chandler to get him to admit it, meanwhile Chandler is hitting on Phoebe to put her off the scent. During this climax of this episode Chandler says that he can't go through with kissing Phoebe and when asked why he he states "because I'm in love with Monica". Monica is touched because this is (supposedly) the first time he has admitted it. She reciprocates in this episode for the first time.
Chandler's first attempt to propose to Monica is interrupted by the appearance of Richard Burke and his date. They end up sitting at the table next to Monica and Chandler, thus making it impossible for Chandler to propose to her.
There were many times Chandler and Monica made out because they started a relationship and got married in Friends. They first started their relationship during Ross and Emily's wedding in London during the end of season 4, The One with Ross's Wedding Part 1 and 2. Also they make out when Chandler leaves to his new job in Tulsa in season 9, prompting Rachel to say cut it out because there is a baby.
Monica and chandler was married before pheobe and mike and rachel and ross never did get married and joey never got married either so according to that Monica and chandler was married the longest but in one episode ross tells pheobe and monica, I was married to Carrol for 8 years how did I not know she was a lesbian?" so according to that ross and carrol was married the longest. Carrol is ross' first wife in which he has his son Ben by.
Ross. Ross.
At the end of Friends, Monica and Chandler save him a room in their new house for when he comes to visit (a 'Joey room') but he stays living in his apartment.ALSO--to find out more about Joey's life after Friends, watch the series Joey.
Monica's first proper boyfriend was Pete Becker throughout the end of Season Three.
Monica and Chandler get engaged at the end of Season 6 and get married at the end of Season 7.
The first person to speak on Friends was Monica Geller, played by Courteney Cox.
A lot of people may think the answer is Joey, but Joey put the turkey on his head to scare Chandler. Monica, however, puts a turkey on her head to make Chandler laugh because he is mad at her.
