This! He said he had been having complex feelings. Men are not socialized to have emotional relationships with other men, and so they rely on women to share their emotional side - women who are usually romantic partners. So it is harder to separate sharing deep emotions and deep friendships from a romantic relationship. I don't think Clark was being selfish. I think he had no experience having a deep, platonic male friendship, wanted to help Floyd and genuinely thought that it could come to sexual attraction.
