Feeling envy

I am remarried to a man who has a big immediate and extended family. His family members are loving and caring. They are always laughing, having fun. I have never seen it heard them arguing. My family is very small and dysfunctional. Nobody is happy or emotionally stable. We are very close to each other but in a very unhealthy way. I find myself feeling envy towards my husband’s family including his grown children.
Here is my model:
C my husband has a great family
T I do not have a family like that
I want my immediate family to be kind, loving and caring
F envy
A I can be resentful with his children
Avoid family gatherings
Not enjoying myself during family gatherings
Can be more distant with my husband

R I am not authentic or happy when I am with his family or kids

Please help me with the intentional model
