How to deal with a jealous sibling?

• I was always told by others how she was jealous of me but I would not believed until now.When I was going to put a child for adoption she was looking to adopt one. Due to financial reason she didn't go through with it.Since then she was looking into buying sperms now she just got injected with it. I am also upset that she told me she just started which was a big lie. I want to tell her how I truly feel specially when we tried for 3rd on building a relationship.

• Answer:

  She probably just thinks you're better than her and wants your attention and to feel equal to you. Could be resulted from people comparing you to her while growing up. I'd say have a talk with her "nicely" and understand how she feels.
