Selfish sister causing drama

[MrsRaspberry]

Am I being unreasonable to be so mean about my sister. Personally i feel shes mean and horrible to me lately. She got jealous over my relationship and didn't speak to me for ages over it. We kind of speak but most of her contact is when her child pesters her to come to visit as he wants to see me and his cousins any other time I don't hear from her.. She recently tried to cause arguments in my relationship despite meeting somebody new herself and when asked by our other sister why she said because she was bored and felt like it. Her new man dumped her after a few dates and she keeps asking our other sister about me and my relationship trying again to stir up drama. Her last boyfriend said he wanted her back and shes taken him back despite the way he dumped her. She's done nothing but slag me off and try to ruin my relationship now her boyfriend wants to see her and her adult son is no longer available to babysit her younger children so shes decided after all the bitching about me to come creeping to my 17year old to ask her for babysitting favours stating that she hasn't seen her fella since mothers day. Am I wrong to feel shes just taking the absolute piss?

Sounds like a cow. You can’t do anything with people like this though. If someone is wired to stir shit and upset people just because they’re bored, your reasoning won’t get through. She just won’t see the problem.

She's "horrible" to you, jealous and tries to cause you pain because she's bored and tries to ruin your relationship. She then asks your daughter to babysit for her secretly without your knowledge.
Of course you're absolutely right to be pissed off. You share genetic material but she doesn't know the meaning of friendship, loyalty or decency.
You have some soul searching to do. Do you want her this involved in your life, backstabbing you at every opportunity? Or would you be happier keeping gbher at arms length at best. You don't owe anyone anything and neither does your 17 year old. Tell her to sling her hook as far as babysitting and secret conversations with your child goes.

She's taking the piss. Daughter asked what time does she need her to babysit tomorrow and she hasn't given a time nor has she said how long shes expected to be out for
