It looks like they aren't happy until they break a couple up. Now, I would never fall for a woman coming on to me because I'm married and it's not worth any woman to betray my wife with an affair. I have been come on to by more than one good looking woman, but just walked away or said "I'm married" The mom seems to push for the offended party to break up just so she and her "Business" seem successful and "righteous".
In this episode the fiancee said that she doesn't go to the dog park to meet guys. She also seemed sincere in her pleading with the guy. She shouldn't have gone to the park, sure, but she probably wanted to feel attractive to someone out in the world and got sucked in. I think that the couple probably could have worked things out and strengthened their relationship with counseling, but the "self righteous" glory hog mom just wanted her victory in busting the woman and pushed the issue saying that the fiancee would have gone on to date another man.
P.S. Momma seems to be a collagen, silicone, face lift, upper middle aged woman, who herself was probably an exotic dancer and can't let go of the need to be glamorous, who wound up with two of her daughters following in her footsteps.
