Watched a french film on tv about 5 years ago. It revolves around multiple couples, over the duration of 1 year. It begins on new years eve and ends on the following new years eve.

The couple that I remember the best is this woman falling in love with a (gay) man that she works with. They remain friends for awhile, even though he knows she has feelings for him. Eventually, he realizes he loves her too, even though hes gay, and they decide to have a relationship. They have the perfect relationship, until the woman subconsciously sabotages the relationship by sleeping with her ex while her boyfriend is away on a business trip. She cheats on him because she thinks he may be hooking up with men behind her back, and she fears that their relationship is too good to be true, even though none of this is true. I only recall that the gay man’s name is Jerome.

Does anyone know the name of this movie? I’ve been trying to find it for years.
