Teresa’s daughters and Melissa

First time watch through and I’m watching the wedding special now. My thing is how sad I feel watching Teresa’s daughters pile on against Joe Gorga and Melissa when it’s so clear to me (especially for the last five seasons) that all of the discord is coming from Teresa never being cordial to Melissa. The whole fact they were mad that the Gorgas stopped coming around because of the cheating accusations it’s sad the girls are so defensive of their mom that they think it’s okay to treat Melissa so poorly. I know it’s natural to stand with your immediate family, but it’s either blind loyalty or we are missing something off camera about Melissa. It’s sad to watch her sweet kids grown into mini Teresas.
