Felt more like a tragedy than a comedy [Spoilers]

I'm of the opinion that at the end, a comedy should leave you with an uplifting feeling, something that this movie doesn't do. The ending was actually quite depressing.

It did work quite well as a comedy up to the ending, then it just fell a part for me.

I did get initial suspicions that Lydia might have had some sort of a slip-up of infedelity.

The first time was when she was talking about having some "doubts" and asking if he had been always faithful. I got the feeling there that she was holding back something that she wanted to say, but in the end couldn't bring herself to do so.

Then when Jarvis was trying to stop Kyle from rushing in and breaking off everything, alarm bells started going off. Then he got on his cellphone in the background and I started thinking: who is he calling? Then Lydia was upstairs and yelled down that she was on the phone. So at that point the mind is already turning and going: she cheated on him with his best friend.

One also has to think, who could she have potentially cheated with, would it have been someone we hadn't seen the entire movie? The choice of men that we had seen in the movie was quite small: Jarvis, Kyle's Boss, and her Boss (mentioned only). Only these 3 were sort of in the right age bracket.

But then, it's marketed as a comedy, so I was hoping that things would be cleared up in a funny way. Sort of like the "teapotting" verbs, where I'm sure 99% of the people thought of the same verbs as Kyles' dad, but in reality they were: "reading" and "fishing".

So while the dildo story was funny and seemed that everything was going to be alright, she then had to say the exact same wording that Jarvis' had used on the fishing trip, and then the suspicions that had arisen earlier were confirmed.

Then the ending is just this confirmation, and Kyle heading out to most likely punch Jarvis, but it cuts off before any definite conclusion.

We're only left guessing that the wedding has really been cancelled, and that Jarvis gets punched (or could it be Kyle who takes a beating?). Leaving one with a very depressing feeling when all is said and done.

Not the way one likes a comedy to end.
