Does she end up with one of the dudes? How does the book conclude?

It's about a female chef / cook who (probably) has catering service of some kind. She caters a man who is busy and she never meets, only saw the pictures in mantle or something and via indirect communications (e-mails / SMS? Forgot T__T). She has the key to his apartment and can put the food in this man's fridge. I also remember one day she met the man's twin or sibling in this man's house (coz she has the key and the man was outside or something), via the request of the man.
Somehow she fell gradually to this man (through their indirect communications) but then a misunderstanding happened, she thought the man is engaged / married / at least involved with a female when in fact it's the man's sibling / twin who is in a relationship.
Please kind fellows, help me find this chick-lit's title as I want to re-read! :)
