So all 3 of my step kids think that I am control their dad in what to say and what to do. I have 2 girls who are 12 and 11 and a son who is 14. They have all resented me.for the past 5 years because I told their dad to not spend all of his checks on them. They don't want to be around me and just use me.for their stuff. They let their mom.talk.bad about me and never defend me. They never bring up all the good i have done for them. Just negative. Has anyone else been in this situation and how so u handle it.
