This photo was taken in London about a week before their break up. Note Wosniacki's feet are planted entirely on the ground. Notice also her knees and feet - and their distance apart. This is consistent with high confidence and an alpha dominance. Both McIlroy's feet and knees are quite close together - and his heels and mid-feet are also off the ground. This is highly indicative of a role-reversing display of low confidence and beta-submissiveness.
A similar configuration can be seen with each of their upper arm's as distanced from their torso's - McIlroy's are much closer while Wozniacki's are considerably further away and forward - again displaying an absolute and relative alpha over her then fiancé's beta emotional tone.
Rory is looking at his phone and probably reading a text; so his relatively beta (almost feminine) body language may have nothing at all to do with the couple's impending break up. However - when viewed in the context of the previous two posts (Nonverbal Communication Analysis No. 2825: Rory McIlroy and Caroline Wozniacki break off their Engagement - Body Language Tells and Nonverbal Communication Analysis No. 2826: Caroline Wozniacki & Rory McIlroy Call Off Their Engagement - Body Language and Dominance) - this nonverbal cluster is highly suggestive of McIlroy's submissiveness and Wosniacki's dominant role in the decision making with regards to the couple's very recent break-up.
