It is not yor sisters fault that he cheats.We would all have reasons to cheat ,to drink,to do whatever because we are not happy with something.She needs to realize that,if her husband was not getting enough attention from her,he would've had to tell her so before he made all this mess. Your sister is not working hard and miss her pleasure to be with her husband on purpose.She is making a living that he enjoys too.He needs to support her in her work or tell her he needs her more around,not go out and find excitement with someone else.He is there only because of the child,then it is time to get it all clear for them two.They need to talk it over,wheter there is enough to stay together and live a family life or is it time to separate the way in two.It would affect the little girl,but they both love her and in time she would be all right with it.The child most of the time does not fuss about the parents not being together,but it bothers her more,if the parents do not care about her.Talk to your sister,make her see it is not her fault,/the cheating/,tell her to make it work if there is still a chance,but otherwise,move on.
