Why did I like/dislike the text?

This text has had its ups and downs in Catch. Tim has went through a lot the last couple of days and it is all so overwhelming to him. He finds a girl he works with and he likes this girl a lot. Her name is Helena and Tim and her do not necessarily get along right away. Tim just toys with her at first and then it becomes something more when she sees Tim there. They talk all night and go home together. The next day at work we find out that they slept together that night. It kind of builds from here and they are talking all the time, hanging out, not being seen together or seen at all for that matter. His mom calls his friend Denny asking where Tim was and he said Tim was at his house. Tim was fortunate that Denny did this for him. Helena has to watch a house and Tim goes over there and stays with her and they went shopping together for food and run into Tim's brother. He sees them and kind of makes fun of those two together. They go about their night and Helena falls asleep on Tim because she was so mad about his brother she drank too fast and passed out. Tim had an orientation the next day and didn't call Helena. This whole part interest me because It sounds so much like a high school affair kind of thing. No one quite is sure what is going on and they just manage not to be seen and then they finally do. I also thought it was weird how they met at a bar and thats where they hit it off at. Tim later finds out that his brother and Helena slept together all in high school and thats why she can not continue the relationship with Tim because she has hurt way to many people.
