How do I deal with my step mother trying to take my dad from me ?

You’ve been reading too many fairy tales. And, I know you’re a teenager, but try and have a little outside perspective. I know it’s hard, but honestly the world does not revolve around you. This woman, knowingly married a man with kids, knowing that she’d have to deal with them. Despite that, she tried to be a parent. No, she is not your mother, but she is married to your father, and deserves some respect. Perhaps, as a mother, she was able to perspective take (see this is something that comes with maturity, the ability to see someone elses point of view) and thought how your mother must feel without you. What a terrible person. How dare she have empathy for some else. Evil witch. And then! She goes and has a baby with the man she loves and is planning on spending the rest of her life with. Wow. She should be tried and hung for that! How dare she create something out of that love. Doesnt she know that he is your father and therefore has no right to a life until you decide he does? You like fighting but you’re the mature one? Thank you. If I ever get it in my head to date someone with kids, I shall just remind myself of this post and stay away.

To answer your question. Stop believing this woman’s sole purpose in life is to get between your father and you. You’re approaching an age where theoretically it is possible for you to perspective take. Which means it is (in theory) possible for you to be able to take another person’s point of view and see where they are coming from. It is possible for you to have some empathy (you know, understanding). Your father married this woman. Either he is a complete idiot and thus has not been able to see all that she has been doing, or perhaps he is able to see that she is not evil, and your perspective has been a little skewed. Think about this. If not for her sake, then for your father’s sake. Because two of the most important people in his life fighting means he is unhappy. And what, you’ll get them to divorce? Hasnt happened yet. And what if you do get them to divorce. Then he’s got another kid he has to visit? If for no other reason than you care about your father, think about it. Stop trying to justify who is right and who is wrong. Because even if you are right, the only person being hurt at the end of the day is your dad.
