Laura Dean Keeps Breaking Up with Me

Rating is low cuz there are several things that dont make sense to me:
1. What does freddy even like about laura? The make out sessions and thats it?
2. Whats the reason behind laura breaking up besides being cruel? Like, for real. She already fools around with everyone so why the need for break ups?
3. The teen pregnancy thing ruined the book for me. Especially the way it happened. Doodle might be a victim but i do not feel bad for her at all. She even said sth like “seeing u w a person as toxic as laura made it seem ok for me to have sex w this married man” Just no. That's immature and disgusting.
4. I understand doodle's dad being pro-choice but he's kind of too relaxed about this whole situation?? Dude, theres a creep out there who got involved w ur daughter
