I do appreciate the honesty... I just don't know why it took 2 years for it to be an issue? Is it wrong for me to ask her about blended family counselling? I know it would be a challenge, but with so much of our lives to live after the children I think it would have been a wise investment. I also think she "thought" too much and did not follow her heart. She would have not been alone in the transition... the kids would adjust as well and with agreed guidelines and expectations I think that the stress could've been mitigated and hopefully wonderful bonds formed.
In a national survey of couples in stepfamilies we found that the top three anticipated stumbling blocks for couples related to children and stepfamily stress. 78% of couples expected difficulties dealing with stepfamily issues, 75% expected children to put a strain on their marriage, and 72% believed creating a stepfamily would stress their marriage (Deal & Olson, The Couple Checkup for Stepfamilies, unpublished manuscript).
They were right! On average, couples in stepfamilies have three times the amount of stress of couples in first marriages during the first few years (see Hetherington, For Better for For Worse: Divorce Reconsidered, 2002, p. 165).
Is there any good news? Yes. With time stress levels for couples in stepfamilies can fall to normal levels found in first marriages. Press on!
