Sad books? romantic books? sad romantic books? lol?

Ok, so im really into like romance books lately (pg-13 stuff k? lol) and along with that I love sad stories that make you cry when you read them. So any suggestions of stuff I might like, I'm currently reading the last song by Nicholas Sparks and its pretty good. I cant really think of any other books Ive read that fit into the category of sad or romantic but yeah, any suggestions at all are good thank you. Oh and like I said, keep it appropriate, like pg-13 hahaha no sex and stuff cuz im only 16 and don't want to read that stuff lol
