I am a new step mom of 3+ years. I have two step children who are now 15 and 12. I met them after I started dating my current husband. He asked them how they like me, they said I was fun. Then we sat them down a couple mos later and told them we were getting married. Radio silence. I met the ex several times at sporting events of the kids and after she met me the whole atmosphere changed, I am 12 years younger than my husband. She started telling the kids that I should be their sister not their step-mom.
