Nervous breakdown anyone? I guess we can feel with the woman. If not you are as much of a jerk than her husband. And while Mr. Ritter is usually more of a nice guy on screen, he couldn't be further away with his role here. Actually he is so far off the cliff, that it starts hurting. Not just the viewer, but the movie as well.
Of course the main character has to have flaws he has to overcome so the audience will root for him in the end. But this is not just a 180 turn. This is like Exorcist like spinning when we arrive towards the end of the movie. So much spinning, that it's almost a surprise not all ended up crawling on the floor.
The thing is, for people to care, you have to walk a fine line. Something Ritter either isn't capable of (charisma-wise) and/or the script isn't giving him a chance. And that is before all the convenient stuff that happens (open doors, smelling only when needed for drama purposes and so forth).
Now every movie has logic issues if you really break them down, but the good ones have saving Graces. Why no one interferes, why the story (for "comedic purposes") just roles on like that ... it's obvious and you have to lower your bar quite a bit - to acknowledge the good intention of the movie and weigh them in a big way. If you can do that - well you probably have already voted dislike on my comment... but good for you and I mean that
