This is going to be long sorry... but well Margo asked...
Ally and Rob have had hidden crushes on eachother for 7 years before they finally start going out, and once that finally happens things start moving fast, and after only a year going out Rob proposes...
Ally is a Freak, and a lot of bad shit happen to her, and her other freak friends and all of the people they are close to because the fact they are freaks. Rob isnt a freak but his sister Ally's best friend is. Rob is used to the crazy shit that happens to the Freaks and now him, but after he is caught right in the middle of two horrible incidents he starts to realize that Ally is risking her life way too much to save his ass. After she nearly dies saving him from creatures in one of the books he and starts to worry that one day he might be responsible for her death.
So feeling like not being with the love of his life will ultimitly save her from a tragic end, he breaks up with her suddenly leaving both of them heart broken beyond belief. Because he is heart broken to ease his pain he goes out to a bar and ends up really really really drunk. Next morning he finds himself in a strange girls bed. That moment of clarity hits him that he feels horrible and could never be with anyone else and the next day comes running to Ally for forgivness... but she is way to confused and hurt to take him back...
For a month they dont talk, until finally Rob pretty much breaks into her house to talk to her, and they talk and they make up and the engagment is back on, but that very same day while with Ally, Rob gets a call from a stranger, a girl, who tells him she is pregnant from the one night drunken stand they had....
DUN DUN DUNNNNN!!! Now Ally (only 20) panics... she never had a father either, and doesnt really know what to do. She loves Rob more then anyone in her life, but now having to deal with baby mamma drama, or having a step kid this early scares the living shit out of her, and she ultimately ends everything, and all contact with the love of her life telling him to do the right thing for his future kid.
Thing is though Rob is still madly in love with Ally, and Ally with him. But now because of the worst luck in the word they just cant be together. Ally eventally finds someone else (her first boyfriend) and marries him and raises two great kids, but Rob well his life ends up more tragic, he decides to marry this girl he got pregnant and at first there happy, but well she is a B*&^% and when they have there thrid child they find out that child is a Freak... and the mother ends up wanting to get rid of the kid and is scared of her and so to save his youngest daughter he devorces the crazed woman and has to raise his youngest alone, and lives in misary for the rest of his life having to pretty much see Ally every day (there daughters are bffs) and he still loves her...
