There was one time end of 2018 my sils were all sitting down and one says "its such a shame my husbands daughters how they turned out", then all 4 looked at me to elaborate. They knew full well how effed up these girls were, their behaviour.
 

It was religious holidays and hubby offered to pick them up to meet his family, they declined saying their stepdad wouldn't allow them (sd's were 14 & 24) and not living with stepdad or bio mum but in a home hubby bought for them. Hubbys sisters were furious why stepdad is calling the shots and refusing to allow sd's visit their dad, its not his right or authority. 

lets not forget, stepdad was having an affair with bio mum before my husband even separated from her. Turns out my sil who lived next door had known about a year prior from neighbours that hubbys exwife was having an affair with her current hubby who was married with 2 kids (her ex high school bf), it really hurt hubby his own sister didn't have the decency to tell him. Her excuse was I didn't wanna cause issues. 
people like that don't get to act like they're decent and should be shown respect now.

exwife, Skids and exwife's family are a total shitshow of drama i told hubby keep them away from me. I've been separated from my husband 2 yrs because of border closures from covid whilst i was finishing my university studies. End of this yr when i visit him with our 2 kids during summer school holidays, hubby has been told adult ss aged 24.5 needs to be out. There is no way we're spending 6 weeks with that idiot kidult in our marital home. He shuns us and makes the vibw so negative.

i've warned my husband if he wants us back end of this yr for those 6 weeks, make sure i don't cross paths with him and that adult is not in our marital home. I've been firm that i will not have any relationship with skids. 

my husband is flying in end of april for muslim new yr which is a big celebration, ss will be left alone in malaysia, where he belongs. Hubby made it very clear in 2018 that none of us wanted to be around him and hubby certainly couldn't bring ss along here to my country and make us feel so unwelcome in our own homes. That he destroyed any relationship with us for nothing. His own mum disowned him, his sisters are under bio mum and stepdads brainwashing and barely have a relationship with him, its so fake and awkward, so ss can spend holidays alone because hubby isn't letting him destroy our quality time together

ss did the usual oh I'll apologise to make it right. Well guess what, he hasn't had any contact with any of is in 4-5 yrs. the last time he apologised because hubby told him to, he mumbled as a 21 yr old "daddy told me to apologise" which made me lose it with hubby. I had 2 toddlers who wanted their sippy cups of milk and was wasting it listening to this loser i just walked away from him. My husband actually prevented him from returning to our home from university for several months to try repair our marriage.

when ss isn't here, its harmonious, the moment he sets foot in, its automatically a toxic negative vibe. Very hostile. Thats not the way home shoupd be and frankly if you're upsetting the healthy dynamics and positive environment in our home, you aren't welcome in it

when eldest sd called her dad 1 day when i was overseas with my 2 kids sitting my university exams, she had the audacity to lie to her dad and claim he abandoned her for me and our 2 kids and never made time for them. My husband did so many times only for every single time for them to cancel last minute or change plans. It just happened the week prior hubby had wanted to go visit his dad as it had been ages and thought he'd bring his daughters along, they cancelled 2 days before by calling their brother, couldn't even have the decency to call my husband.

the reason was stepdad wouldn't allow them to visit. We hadn't been with my husband for about 2.5 months at that point and hubby messages me saying if he had know all along, he would have flown to us for a long weekend holiday. I was honest and told hubby he was an idiot for not seeing this long ago because every single time it happened

Then and there i told him that when we made plans, they didn't change to accommodate his kids because his kids have no decency or courtesy and i refuse to adjust our plans to accommodate them like they're something special.

ss once demanded hubby leave our mini getaway to pick him up from home and take him to uni. Hubby said nocl, that we were on a mini holiday and he could arrange an uber. Took my husband 3 yrs to get to that point and realize this is ridiculous. Its all a game to skids to prove they are the ultimate real first family

Has it occurred to him to think what might happen if your granddaughter told anyone at school that whatever-she-calls-him is stealing her underwear?
