The couple are lifelong friends that decide to date. Less than two months into this, she decides he is "the one" and wants to spring the "L" word on him. She does this by getting a key to his place from an assistant, putting pots of plants on his property, then going inside to cook him a meal. He comes home after a bad day with architectural clients and thinks someone has broken in. When he sees her and gets irritated, she responds by tossing the dinner in the trash, breaking his dishes in the sink and screaming at him that he is a commitment-phobe. She needs the fairy tale and kids and marriage, but he's too afraid to love her back. Then he spends the last of this book groveling after she storms off in a huff, including having three of her friends treat him like utter crap before allowing him to apologize and propose marriage.
Here's the thing: If I found an SO in my house with a set of keys I did not give them, putting stuff in my home that I did not ask for and screaming at me about marriage after a really shitty day two months into a relationship, my response would be to open the fridge, grab a beer, and say, "This is called trespassing, plus you broke my shit during your tantrum...so see you when I see you." And forget about groveling to anyone in the aftermath. I fight my own battles, so should they.
