Xander and Yoli message situation

How do we feel about the whole selfie situation between Xander and Yoli in episode six? It’s was so awkward for me to watch, especially with Mel not knowing about the picture situation and was only told about supposed messages. And for them to continue to express how much they love each other, flirting and holding hands while as if their partners weren’t in the same room. Especially with Yoli telling Mel that she was going to talk to Mildred but really excused herself to go see Xander. Does this feel wrong to anyone else?
