children weadle money out of parents - its what they do, esp. teenagers. being unggrateful is also par for the course. they sound normal to me. the only thing i would havea word with your dh about is attitude. talking to someone with attitude is unacceptable in my house. we talk to each other with respect - lots of jokes huge amounts of sarcasm and double entandre.
all kids think their siblings ger more or have had more. my son (17) asked if his GF could move in. i said no, however there had been a president with my older son. so it's not fair apparently - tough shit - neither is life is my reply.
i think its hugely unhelpful to you to suggest that if you had children, you would learn to just let a lot of things go. that you would be better equipped to understand. but it's true.
you don't have these kids that often. they are entitled totime with their dad. a family breakup probably hit them hard emotionally. they are dealing with you too.
if you want to keep your dh - you really have to be nice to the kids. becuase the kids will soon reach adulthood and you dont want them being adults and hating your guts.
its like i have tried to be nice to my eldest sons gf. i know he loves her very much and that if i want him to remain in my life i should be civil to a scheming horrible cow that is totally wrong for him.
now i knew this. still it came to a head and i told her what i thought after a particular situation. I haven;t seen my son since. i knew it would happen.
so the moral of the story is, if not for the kids, for the DH.
youneed to discuss your role with him. what boundries you can set, what things you can get them to do etc.
and try and plan some activities. have you tried baking a cake with them for example?
get them to bake a cake for their dad. get the kitchen dirty and make something, cock it up and laugh over it. presenting dad with something really pants but its the time together thats the thing - even if you end up tidying it up after.
choosing a scary film, making popcorn...
and you really need to get out of the 'my' money thing. his kids are his blood and his life. if you consider yourself a part of his life then the 'my' money thing isn't going to work.
teenagers can be obnoxious and really pants - BUT if you handle things the right way, make an effort to have shared experiences with them, then they can have the sharpest wit, the best laughter and be an absolute joy for company.
