What's the name of this movie? *Updated*?

Okay i think i can give a better description now. Okay i saw a movie trailer the other day and it's about a guy who has perfect friends and a perfrect girlfriend and now that he's 30 his life is how he pictured it when he was younger. But he wants something diffrent outta life and he thinks life's moving to fast untill he meets a girl who's more outgoing and carefree then his current girlfriend. In the trailer his current girlfriend suggests they move in together, and later on in the trailer she kicks him out and he sleeps on the door step. Any help? (No it's not 13 going on 30 cause it's about a guy) I'd really apperciate it.
