I have a 4 year old step son who I adore and love as he were my own child. We share custody with his mother who in almost 3 years now still refuses to meet me. When it's just him, his sister ( mine & his fathers daughter ) and I he's great. He treats me wonderful but as soon as his father comes home he totally flips on me. He's extremely disrespectful, rude and just plain out mean. There has been a couple times he's actually hit me for getting onto him.
