Listen ... only you are going to stand up for yourself ... so step up and do it now.
I spend so much on stuff for both my nieces
Stop doing this and start saving more money. I think you'll need it.
I was freelancing when I took time off to help SIL and MIL look after SIL's new born baby. So i lost out on 4 weeks wage. I did it because I thought it would benefit everyone. Especially my MIL, I know how tired she often is so I did it more for her than SIL. Little did i know SIL would not appreciate it at all.
So you're going to get taken advantage of again?
Am I just being naively optimistic?
Yes you are.
I suffered a MC a few weeks ago, and go pretty much 0 sympathy from SIL. This comes after a life threatening ovarian cyst rupturing.
You're allowing yourself to be taken advantage of. You're going to have your own child. Stop spending on your nieces like that, especially as it's not appreciated.
It amazes me that we live together and she just doesn't care about me
Why does it amaze you? She's selfish.
I've let it get to far and now I'm stuck.
No you're not stuck. Start standing up for yourself.
I'm mindful of your culture, but I also originate from a culture where inlaws can try and take advantage... but I don't let them.
I've had to stand my ground and I don't rely on my DH to fight my battles with his family. He's crap at confrontation.
I would pull any stunt to get away from being a childminder your SIL. It's time for heavy hints and talk about a return to work.
No matter what your culture, being financially independent gives you options. It means you don't have to put up with crap from your DH or anyone else.
What if you decide your mum will look after your baby and you'll return to work. I don't mean work in the house either. Perhaps you could come in all happy to SIL ... tell her you're mum has agreed to look after the baby to allow you to work full time.
That should wipe the smile of her face.
