🆘 WATTPAD PLEASE HELP ME FIND THIS BOOK

SOS!!!! I would really love it if someone could try and help me find this book again.

I faintly remember it being about this couple (girl and boy) and I believe they were in highscool. The boy had mental issues (PTSD probably) that were a result from his mom locking him in the closet and abusing him. He had a hard time speaking his mind and did alot of weird things and she didn't understand that he was trying to show her his love. And I believe he was the bad boy in the school (it's not Room 234 Virgin or Run Ruby Run). He had a group of bad boy friends that help the girl to understand and love the traumatized boy.

I remember the final scene was them causally watching a movie on the couch, as they had been together for a long time. In the middle of the movie he randomly put the ring on her finger and doesn't say a word. It's because he was never taught how to propose and the only way he knew was to surprise her with the ring. She found in hilarious but endearing and she said yes.

I also remember that is was quite a well off book. I mean that is was well known and popular at the time. Hopefully someone will find this and be able to help me out.

Best wishes,

SALLIE
