He accepts, but soon after Wyatt's mother Quinn Forrester catches them in the act when they're in bed together. Quinn is furious. She drags Katie out of her own bed and threatens her. Wyatt demands from his mother to accept their relationship or she won't be welcome in his life. Wyatt assures Katie that his mother will come around.

Wyatt tells his brother Liam Spencer that he has a romance with Katie and he feels something for her. He confessed that he asked Katie for "no strings attached", but in reality he wants a serious relationship with her. After talking to his brother Wyatt is ready to confess his feelings to Katie and prepares a romantic evening for them. Wyatt comes to Katie's home and decides to look at the Forrester's home where Brooke's and Ridge's wedding takes place. Knowing that Katie is there he looks through a telescope in hopes that he will see her. He does spot Katie, but not alone. To his horror Katie and Thorne shared a kiss. Wyatt feels hurt and betrayed despite them not being officially a couple. When Katie comes home Wyatt asks Katie to think over their future and points out that their relationship is a danger to his position at Spencer Publications. The two decided to break up, but soon after Wyatt left a message for Katie in which he asked her to think things over.

Official relationship/ Bill's strong disapproval
Wyatt asked Katie to see him. He confesses that he wanted to break up with her because he saw her and Thorne kissing. Wyatt also informed Katie that he left her a message and then Katie realized that Thorne (who actively tried to win her over) has to delete it before she could get it. The two confess love to one another and decide that they must tell everyone about their relationship. Wyatt asked Katie for her hand and she happily agreed.

Wyatt and Katie informed Bill about their engagement. Wyatt's father wanted them to stop their relationship and he threatened Wyatt with disinheritance. Bill doesn't stop there and tells Katie that he will try to take their son Will Spencer from her. Wyatt is so angry that he tells him that he regrets that Sally Spectra II missed and didn't shot him. Bill is furious and breaks the "Spencer necklace" from Wyatt's neck. Wyatt tried to assure Katie that Bill is just talking and he won't try to take Will from her.

When Wyatt and Katie inform Eric and Quinn that they are engaged also Quinn is opposed, but Eric convinces his wife to accept the union. Wyatt tells them about Bill's reaction and confesses that while Bill slept with his own daughter in law Steffy Forrester he is calling his relationship with his ex wife wrong.

In March 2018 Katie is terrified when she gets documents that prove Bill was not joking and he wants to take Will from her. Wyatt assures his fiance once again that it won't happen as he won't let it happen. Soon after Bill got shot. Katie finds him and calls the ambulance. In the hospital Katie asks Wyatt if he tried to kill Bill, but he said that he had nothing to do with it.

In April 2018 Wyatt and Katie wonder if Bill changed his mind about their relationship after his close encounter with death, but when Bill walks out of the hospital he vows to make them pay for their romance. Bill, while trying to become a step father to his own granddaughter tells that he won't allow Wyatt to become a step father to his own brother. Bill offers Wyatt that he will have a strong position at the company in few years if he will end things with Katie. The Logan woman wants Wyatt to be happy and is tired of the war Bill has created. The two call off their engagement, but continue to see each other in secret. Wyatt tells Bill that he left Katie and Bill lies to Wyatt that he and Liam's wife Steffy Forrester not only shared a passionate night months ago, but are having an on going affair. Wyatt can't believe it, but Bill makes his son believe that is happening by manipulating. Wyatt tells his brother about Bill's and Liam's affair. Later on Wyatt found out the truth and Bill offered him expensive gifts to keep his mouth shut.

The end (2018)
At first Wyatt accepted Bill's gifts in exchange for silence, but he feels guilty. He confesses to Katie and she tells him that he should be silent and allow her niece Hope Logan to marry his brother because they are very much in love. She reminds Wyatt that Bill and Steffy have a strong bond. Wyatt is torn, but in the end decides to reveal the truth to his brother. Katie is disappointed that her niece has to get hurt, but she admits that it was wrong of her to encourage Wyatt to keep the truth to himself.

Wyatt and Katie soon end their relationship because it has no future with so many obstacles that they can't fight with.
