Step mom

Heaven

So my boyfriend and I just had a baby together. I have a son from and previous relationship and he has two sons from a previous relationship. His youngest son is 3 and he does NOT like me. He cries when he is around me, tells me he hates me and now he is telling lies about me that make me want to scream because they are so outlandish, it just doesn’t make any sense. This causes so much tension in our relationship because I feel like I’m on edge on the time when his youngest is at our home.. it’s getting pretty unbearable. I know I sound crazy because he is so young but I’m going crazy trying to be a “friend” to the little guy but he wants nothing to do with me.. I need help!
