Actually I wanted to see that movie again but don't remember the name. Story goes like this, if anyone could recall.
A girl had two options of guys, one of which is struggling writer and one is rich successful ad agency owner. She lives with her brother and discusses her two simultaneous relationship with him. Brother is reimbursed for a chewing gum ad.
In the end after dating two guys at same time she decides that she will marry rich guy. But as usual writer guy runs for the girl and girl realises her love for him and miss her flight intentionally. At end both meet.
Probably shot in Washington DC or maybe Texas. Movie is around 2003-2009. Probable IMDb rating could be 5-6. I have seen it at friends place, 3 years ago.
