I think it's an act she is putting on the challenge with LI these days is standing out and she is definitely doing that!
I think it's an act. But I do think its rooted in a self esteem issue.
I think she believes the way to get any man is make it clear he doesnt have to work to get into her pants. Which, to be fair, probably works alot on Real Life.
But not so much if people are in in Love Island to raise their profile. Tommy is there to raise is celeb profile. I think he knows, long term that kissing Maura and going with her wont produce a long term relationship and make him look like a total dick.
