The decision by Tommy leaves Joe fearing for his future in the Love Island villa after leaving him without a girl.
In the tense scenes on the ITV show, Tommy and Curtis Pritchard were told they had to pick a girl they had connected with the couple up with.
The pair had been getting to know the girls earlier in the episode and Tommy had set his sites on Lucie and Amber Gill.
Then, at the end of the episode he chose to split Joe and Lucie up so he could have Lucie all to himself and fans were left heartbroken by the decision.
They took to Twitter to react to the shocking news and blast Tommy for splitting up the pair.
One fan reacted: “Wow TOMMY JUST DID THAT. Soz I don’t like Tommy anymore. Bro code is clearly non existent.”
Another added: “Just shows you the type of guy Tommy is.”
Other mourned the end of Joe and Lucie’s blossoming romance: “Okay, my heart is truly shattered for Joe right now. Why’s Tommy got to go and break them up, praying that Lucie makes her way back to Joe because I’m all for team Jocie!!!”
Another added: “I feel so bad for Lucie and Joe, they were such a cute couple. Can’t believe Tommy done that. What a mug.”
He had previously stated earlier that he did not want to split the pair up after getting on well with Lucie.
Other fans defended his actions as it is the premise of the show to find the best couples and if Tommy thinks Lucie is right for him then he is right to go for it.
Lucie was evidently uncomfortable with the situation as it now leaves her romance with Joe clouded in doubt.
Another new couple emerged from the show and that was Curtis and Amy Hart after the pair have really hit it off.
Curtis announced first he was going to choose Amy and fans were relieved for her after her partner Anton Danyluk had even seen with a wandering eye.
Meanwhile, fans had been left confused after Tommy received a text telling him it was time for him to choose which islander he wanted to couple up with along with Curtis Pritchard.
