@AlexA I think you are a bit naive here :) Jealousy is a very normal thing for every human being and has nothing to do with religion. Some are more jealous, some less and i doubt that you as child are aware if your father has these feelings or not except if he showed them prior. I do now know your father, but i am just saying that it might be less about teaching you but about being uncomfortable with another man being in the house with your mom when he possibly is not :D — MansNotHot 36 secs ago
