If you're in a first marriage and struggling please don't fantasize that divorcing and starting over with someone else is the answer. As an expert in stepfamilies I can tell you that stepfamily marriages have a high degree of difficulty and a higher divorce rate to prove it. No, baring extreme circumstances you're better to stay in the marriage you're in and make it work. If you're in a stepfamily marriage and struggling the same applies to you. Making this marriage your last is well worth it.
