Answer:
<h2>A. "has begun to neglect his friends"</h2>
Explanation:
Neglecting his friends is a dangerous dating situation, because Evan is completely depending on Lara, emotionally and socially, which is a pretty a bad scenario, because Evan will soon start to manifest possessive behaviours towards Lara, which include pathological jealousy, ending in aggressive situations.
On the other hand, a healthy relationship must have several conditions or characteristics as trust, mutual respect, compromise, good communication, emotional control, understanding, problem solving, self-confidence, and one of the most important <em>individuality. </em>
Individuality is an important ingredient here, because a couple is formed by two individuals, who have self-needs and own friends. Also, individuality defines your social skills, aspirations, motivations, and other needed characteristics to have wellness.
For all these reason, neglecting his friends is the right answer.
