so quick backstory I've been married to my DH for 3 years now, we have 2 children together and 1 on the way. He has 3 children from a previous marriage (SS14, SD13, & SS12). Since about December of last year they started living with us full time, no change of custody (it was just 50/50) but they were living with us full time. SD13 & SS14 showed some interest in still visiting BM from time to time (like once a month) but SS12 wanted nothing to do with BM. All 3 have told me how horrible BM is, from choosing her boyfriends over them, a house with black mold, never washing clothes, only having eggs to eat and BM would buy McDonalds for herself, roaches in the house, buying herself designer items while living in a 3 bedroom trailer with 5 children. The list goes on. BM made SD13 and her other two girls make false accusations against DH, and other family on DH side to try to get full custody (this was post divorce) over Covid we started a relationship with my step kids other two sisters they are 17 & 18. They told us a lot about Eveyrhing that went on about the house and also told us about the mom making up lies to CPS and ect. So as far as we knew all of BM kids hated her. Well about a month ago SD13 took a huge interest in visiting BM. We usually cut the visits short because we usually have plans pretty often. She went on Labor Day and we texted her around 3 and asked if she could get home around 4 because we were having food delivered. She told me she wanted to stay with her mom and that she texted her dad already. Long story short she hasn't came back, has only went to school twice in a month period and her sisters are defending her, talking shit about me, and enabling her to skip school (her sister 17 is a drop out) DH didn't fight to get SD back because SS's were very scared that BM was going to come take them. The following day BM tried saying she was going to come pick up SS's. Usually she asks them if they want to go but this time she didnt ask them, so DH told her no. SS12 wants nothing to do with BM and desperatley wants me to adopt him. SS14 is hurt and feels betrayed by both BM and sisters. SD also was claming she left because of me. which didnt make sense because she had me in her phone under mom, told all her friends she considers me her mom since her mom sucks and hugged me and told me she loves me before she left. my SKids have a completely different life here, we just got a house custom built, everyone has their own rooms, they have iPhones, name brand clothes, their own TVs in their rooms, cupboards full of food and snacks... DH makes pretty good money and puts it all towards our children. Why on earth would SD leave all of that for a place that's literally dirty and BM leaves them all the time to go sleep w random men?????? I treated her like my own daughter and loved her all the same. I feel so hurt. Idk what to think or do, looking for some encouraging words or similar stories. DH is very hurt and told SD she isnt welcome back especially after she stopped going to school and basically told BM that he isn't helping dig out SD when she ruins her life.
