It doesn't sound as though she felt any kind of sexual attraction towards the OP. However, it does sound as though she began feeling uncomfortable. That discomfort could simply be the result of a change in the relationship dynamic. It sounds as though the T began to fear the OP (ie fear of slashing tires) and that there started to be arguments (provoking) and tension. Her shifting attitude could easily manifest itself in a desire to create physical distance and not want to touch/hold so closely anymore.
