To the Step-Moms and Dads here, as a step-child I just want to give a big thank you.
In the beginning you will always be seen as the villain. You will be compared to 'my real mom' or 'my real dad' and it will hurt. You will have to put up with us saying hurtful things even the 'H' word.
If you can make it through this phase (which may last years) we will soften, begin to trust, and yes even love. It took me my whole life to learn to appreciate the sacrifices my Step-parents made for me. Now that I am an adult I just want to say to all of you step parents who are waiting to be appreciated by your stepkids that the day will come. Have patience and thank you!
