Help Remembering A Tv Prog Title, Please

[Cloverjo]

A couple years ago, there was an American tv drama about a couple, in their thirties I guess, who were having marital and sexual problems. They had the man's friend and the woman's sister staying with them.
The last episode I saw ended with the woman just about to sleep with a colleague in a hotel on a work trip, while the man dumped the kids with a neighbour to drive to the hotel to surprise her.
Does anyone know the programme I mean, what it's called and if it's available to watch? Thank you

Any idea exactly when it was on? Which channel? Who was in it? Setting/Location?

[Cloverjo]

I can't remember when it was on. The channel was probably Sky Atlantic. I can't remember the names of any of the actors. The man was a geeky/nerdy type. The woman had shoulder length curly dark hair. Her sister had long dark hair and was very slim. Not much to go on, I know.
Thank you for replying.

Found it! It's called Togetherness, in case anyone was wondering - unlikely! - and apparently the next series starts on Sky Atlantic on Feb 22.

Think i might have seen a few episodes myself- did the wife join a dating site and then pop off to meet a black guy in a hotel bar?

It might've been that one, B00. . Sounds about right, although I don't remember a black guy.
