Yep, I'm a stepmonster. 10 years for me and they are grown, in their 30's. I could write all day what I've been through but it boils down to them not being able to accept a woman in their dad's life or feeling they can interject their thoughts into our marriage. And, there's my husband being afraid they might go away if they think I'm taking their place. It has become so stupid I don't go there anymore. I just back away and let the fur fly but I do think my husband is slowly coming around.
