I watched this move a few years ago I think. I remember a guy being friends with a woman, whos husband leaves right when she gets pregnant to find himself on a mountain or something. He helps her out a lot and I think he is also in a relationship or just out of one and she tries to help him. A few things happen, I think he sees her partially naked and she just doesnt care cause shes in mom/I dont care mode. This kind of moves things along and they end up falling in love. The husband comes back confused and ends up punching the dude in the face and then leaves for real because she doesnt want him anymore.
