I am happiest when my step kid leaves?

Nope! You are completely wrong. I was raised as an only child with both of my parents still happily married. Included lots of cousins and extended family as well. My family life was and still is great. I have nothing against step parents only pieces of shit like you who chose to get with a woman with kids and was too selfish to try and bond with her kid. You are just trolling to get under our skin, so everything you say is invalid.
