Absolutely!! Currently, being both a Step Mom and a Step Daughter, also, with friends who are Step Daughters, I can tell you, there really can be a fine line here.
Women together at the best of times can make a royal mess of things. Kick it up a notch by putting them in a situation where they are vying for the love and attention of the same man, and you just might have a recipe for disaster…or not, all depending upon the women, and the Man involved.
The Husband, and the Dad, plays an integral role in the successful acclimation of his daughter(s) and new Wife, and how he chooses to command himself can indeed lend itself to the success or failure of this sometimes tricky relationship. That being said however, he cannot act alone.
It is also incumbent upon the women in this story to do their part, behave fairly and let love lead. Expecting communication funneled through Dear Old Dad to heal wounds or repair rifts is less than a band-aid solution, for, as soon as you think you might be safe to swim again, the band aid falls off in the water :)
Girls, there are two fundamentally different types and levels of love going on here. He loves you both, just differently. There is no competition, unless you create it. Dad didn’t set out thinking it’d be fun to pair the two of you up to see who fights the better fight. You were brought together because of Love.
You may not love one another, you may not even like each other, but you both have an important thing in common, and that is your love for the man who brought the two of you together. Honour Him by seeking to understand one another. Honour Him by giving it your best shot at civility. And honour Him by accepting the fact that he needs both of you in his life to be truly happy and act accordingly…OK :)
