Who wrote this drivel?

I'm referring specifically about 2 scenes which, in my opinion, weren't anything near being realistic. For a husband who's disenchanted with his wife's reluctance to forgive and get back together with him, his reaction was way off the mark. At least that's how I see it. For example, what husband would allow another man whom he believes is competing for his wife's affection to get away with interfering in his relationship without doing something about it? Also, when you believe you have lost and the marriage is in fact over, why not take it like a man?

In the scene where he enters the restaurant with his kids and sees his wife sitting at the bar with her boss (the man whom he suspects is vying for his wife's affection), why just turn away and leave? It doesn't make sense. He should have just walked up to her and invited her to join him and the kids for lunch. It certainly would have sent a message to the boss. The other bothersome scene was at the end when he thought he had failed in getting her back. Seeing his wife with her boss, he runs like a spoiled kid who didn't get his way. He should have done either one of two things. He should have either kicked the bosses ass for interrupting their family's enjoyment of the party or if he believed he gave it his best shot just walked away and gone back to Los Angeles and get on with his life. He just looked too wimpy in the way he reacted.

I won't bother questioning why this actor was cast in the role since others have. I'll just say that I wish it had been someone else.
