"I just thought I wanna get you all together in a group and say thanks for spending parts of your life with me even if it was a long time or a short time Bella lol."
Ex-girlfriend Gemma wrote back "wow" but Bella was a little more frank in her response: "F*** off Tom, seriously. You really are a f****** disgusting p****."
At that point ex-girlfriend Lisa left the chat without making a comment.
Bella added: "Do you really think this is funny? Putting me in a group with a girl I know you f****** slept with while we were together?!"
At this point ex-girlfriend Steph chimes in: "Ok woah pet think what you want but Tom said you weren't together after the holiday coz you f**** it."
An incensed Bella replies: "We were together 'pet' and Tom just lied to you like he does to everyone. He's a f****** pig."
At this point Tom decides to set the record straight and writes: "Erm no Bella we weren't together coz you went back up to Brid and just f***** me off and I sent you a message saying we were over."
An outraged Bella has clearly had enough and vehemently replies: "ON FACEBOOK WHICH YOU SHOULD HAVE KNOWN I NEVER F****** CHECK YOU P****."
With the entire conversation descending into farce Gemma mentions how hilarious she is finding the exchange, prompting an enraged Bella to direct her wrath at her: "And who the f*** are you!?!?!?"
But an unruffled Gemma replies: "Me n Tom were together in school but we're still mates find ur chill love."
Tom, who is clearly enjoying himself, adds: "I just wanted to wish you all merry Christmas and Bella you've ruined it all again."
After a few more choice swear words on their parts an indignant Bella and Steph leave the conversation, leaving just a tipsy Tom and Gemma in the conversation.
Tom wrote: "Well that went well. How's things Gem? Fancy a drink?"
Gemma replies: "I was a bit s*** until this convo - my nan passed away just before Christmas so I could do with a drink. When you you fancy it? xx."
