second sisterhood of the traveling pants part4

I thought Lena and Kostos were good for each other, I guess the author did not want them to be together. Everything between the two was really good, then suddenly his letters were getting short and he was writing differently. Kostos also said that he could not go up the next weekend to see Lena, which that really upset her. Lena did not understand what was going on and finally he just broke it off. She knew it was coming but she did not know for sure. Anyways the break up was really tough on Lena, all of her friends were very worried about her. Also, she found out her Grandpa Bapi died. So Lena and her whole family went to Greece to have the funeral. Lena wanted to see Kostos so everything would be better. But when Lena saw Kostos, he was with another girls. When her Grandma introduced Lena to the other girl, she said this is Kostos fiancé. I just felt so sorry for Lena, because she did not know the reason why Kostos was acting different. She has been through a lot this summer.
