I don't want my mom's bf over all the time and I'm getting in the way of their relationship.
Do you think he's getting in between you and your mom?
No, I like him and I feel like he's a part of my family.
Well if you like the guy and feel like he's part of the family, I don't see what the problem is. You shouldn't interfere in your mother's relationships. Let her be happy!
You're right, I don't know why I was acting that way, maybe I was jealous.
I am glad that you realize what you were feeling and maybe now you can improve your behavior and have a better relationship with him.
