When Brian and Sarah began dating, her friends were envious. Brian was smart, sensitive, funny, athletic, and good-looking. For the first couple of months, Sarah seemed happy. She started to miss her friends and family, though, because she was spending more time with Brian and less time with everyone else. That seemed easier than dealing with Brian's endless questions. He worried about what she was doing at every moment of the day. Sarah's friends became concerned when her behavior started to change. She lost interest in the things she once enjoyed, like swim meets and going to the mall. She became secretive and moody. When her friends asked if she was having trouble with Brian, she denied that anything was wrong. Healthy relationships involve respect, trust, and consideration for the other person. Sadly, lots of relationships don't have these qualities — and many turn abusive. In fact, 1 in 11 high school students report being physically hurt by a date. People in abusive relationships sometimes mistake the abuse for intense feelings of caring or concern. It can even seem flattering. Think of a friend whose boyfriend or girlfriend is insanely jealous: Maybe it seems like your friend's partner really cares. But actually, excessive jealousy and controlling behavior are not signs of affection at all. Love involves respect and trust; it doesn't mean constantly worrying about the possible end of the relationship
