Step parents are supposed to act like parents

So apparently step moms are supposed to act like mothers because they got in a relationship with someone that has kids but not be appreciated for what they do. If they treat them differently than their own kids, women complain and if they treat them like their own kids they say we are not their mothers! I feel like a lot of these women are just going through relationships where the dads now have wives and are on the other side. What we do as mothers for them are very valuable and cannot be given on the streets by anyone. I have seen a lot of posts here about them replacing fathers and their kids calling them dad because they deserve it. Then, that is ok. But if its about other women involved other than u, step mothers should stay the fuck away. How would u feel if u raised ur own child, sacrificed so much for them and then they grow up and slap u in the face by not respecting u as a mother? Or never see u as their mom? Dont be selfish. I love my step kids as my own, and i will always be that shadow that protects them for life even if i stay as a shadow in the dark. Even if their mom is bitter about me being around. I give away my weekends to spend time with these beautiful children while their mom has a fun weekend doing what she couldnt do when she was dating my husband even though i am way younger than her. EVERY weekend. I have to be at her home picking them up at whatever time she tells my husband because she has to go out so i need to be on time (he works a lot so he cant make it but he still sees them no matter what) she gets angry because i take care of them not him sometimes because has has to WORK! She doesnt stay with them every minute they are with her because she is got to work so? Why hypocrisy? She complains about him only seing them Friday through sunday during school but she wont let him see them during the week because of school. During summer we have them Thursday through Tuesday! She sees them one day and shes never even at home! I dont care what she does, says or wants. All i care is that they are a huge part of my life and i feel so bless to have them in it. I do it for them not for her. And i will always be the shadow in the dark.
