DEAR ABBY: I am happily married to a great man. I have a young daughter from a previous marriage, and my husband has two teenagers, a boy and girl, from a prior marriage. Like many blended families, we have our struggles, but one is becoming increasingly difficult to deal with.
I don't know how to put this tastefully, but I'll state it this way: My stepchildren are "too close," if you know what I mean. They flirt, constantly touch each other and playfully tease each other. (A few people have even mistaken them for a couple.) My husband doesn't seem to notice this unhealthy behavior. How can I get through to my husband or deal with this? -- REPULSED IN PENNSYLVANIA
DEAR REPULSED: Was the relationship between your husband's children making you uncomfortable before you married their father? If so, did you bring it to his attention at that time?
Family relationships can vary, and because I haven't witnessed what you have observed, I can't advise you other than to suggest that family counseling might be in order to determine whether the kids have a normal sibling relationship or if it has gone over the line.
