Hi C.,
I am a new stepMom also since June 2006 and my husband and my SD(12 y.o) are also very close. I also feel a bit jealous sometimes when my hubby cuddles her or let her sit on his lap for a few seconds while watching TV but i tried my best to cut that feeling of jealousy away because I know it's not productive. In my mind, I tell myself the love he has for his daughter is different from the love he has for me. And besides, when it's time for us to sleep, he would cuddle only me. hehehe
I also have a very close friend who has stepchildren and she shared with me that she had a hard time dealing with the situation when her husband spends time with his children as she is a possessive type of woman saying: she wanted her husband for herself alone". But she asked God to help her go through with it, process it, grow more mature with it and now it does not bother her anymore.
What I am trying to say is, yes - it's human nature to feel what you feel, it's understandable but try to control it or deal with it positively so that it will not cause strain on your relationship with your husband.
Personally, I try to get closer with my stepdaughter as she likes me very much. She talks to me everyday and shares all her thoughts on me esp, about crushes with boys as she can't talk about it freely with her Dad. I told her I love her like my own daughter so she trusts me. At first, it was my husband who appeared jealous of his daughter's time which is spent more talking with me as I'm not working yet. When I sense that, I tried to gradually kept a little distance from her (not very obviously that she would wonder what happened, why I changed) but only so that her Dad would not feel insecure that I have stolen her daughter's heart away from him.
But when her Dad is not watching, or not at home - I build my relationship with her again by listening to her chitchat no matter how irrelevant they are or sometimes she talks nonsense. She's just a kid anyway and she amazed me sometimes and takes away my boredom by making me laugh with her silly comments.
I just wanted to be the best stepMother in the world as i never want to be called a wicked stepMom (remember the FiryTales? :). I guess, it's one of my ambition in life to be a good stepmom when I am given the opportunity. And here it is...
My husband claims that he is a good disciplinarian also and he grounds her for her mistakes or negligence but at the same time, he also spoils her a lot with good and expensive things that she could think about (IPOD, CELLPHONE, etc.)But I don't dwell on it and I focus my mind on other bigger problems and challenges that I face with my marriage.
I am not sure if my sharing with you my own story helps to give you a different perspective. I hope it does...
Happy new Year to you!!!
