She doesn't want me anymore...

I went and stayed with my ex step mom not too long ago and I was just trying to make plans to go stay with her again because we had so much fun the first time. Well she doesn't want me to come down again now... She doesn't want to tell me why, but I think it's cause her new guy doesn't like me. This really hurts my feelings because she has been like a mom to me since I was like 9 years old.... 😞
