"I'm Worried, I'm so worried"

This few days feeling quite vex becos of dd's carcar prob abit worried that she can't save enuff for the car or because of the car she have to live like a pauper... u can say I am now pondering whether urging her to buy the car is a good thing or a bad thing...
Reasons why I encourage to buy:
1)It's always her dream to own her car, and I feel she'll b happier if she do have one.
2)Car prices are cheap now, may not be able to afford in the future
3)wan to make use of this opportunity to let her learn how to save money
4)Prevent her from giving her parents more money (>500) so as to protect herself
5)Even if she don't buy, her money will also go to some other place and b lost forever without a trace.
6)Let her gain some "face" back.

Reasons why I am having 2nd tots:
1)she can't curb herself from spending more $$ even though she had planned to. She dosen't have the self-discipline and/or she is just not firm enough to put plans into actions.
2)worried that she'll have to suffer due to suddenly having much less to spend
3)Her parents will keep "borrowing" $200-$300 from her every month(on top of her allowance and she don't know how to reject them), To be honest she can't afford to lend them $200 when she is paying for the car lor.

just recieved a car from the car agent,that our orange picanto is coming, already paid upfront $2k now need to pay another $800 for 1st instalment and insurance. meaning I'll have to come up with another $400. Actually it's quite a heartache for me to part with the $400. cos it really take much effort for me to save up to the amt of $$ i have now. I hope this will be a lesson to her to teach her the virtues of savings. I am still a student yet i managed to amass $6K and at 1 pt I have $8K. It's not easy considering I have almost no income. But i guess this time the $400 I have to give to help her fufill her dreams, just hope it's not a short-lived 1. To be honest, I don't have much expectations of recouping the $2.4K from her and i don't want to add to her burden. If she can't "repay" the "loan" then nvm lor. I'll just slowly take my time to save back the $$ again but I guess $2.4k is just abt the max I can part with cos i don't want the $$ in my UOB to drop below $5K unless there's a emergency then that I've nothing to say.
I've been telling my dd to save up some years already, but that time she still have to study and thus have to come up with alot of $$ every year to pay her PT degree fees.Somemore she still have to satisfy her parent's "greed" for more allowance.( To me it's just to brag abt it in front of relatives n neighbours) thus i dont't blame her for having little or no savings that time. But it's been 6 months since she grad and though she's working her savings is still less than $2K.(see my FOR pt 3 and 5).Put it crudely I am not working, my income is almost 0 mabbe she can take a page frm me, I still managed to save a few $Ks, I do believe if I can do it so can the rest of the people even more so for those who are working and have a stable income. Perharps if she had heeded my advice earlier and start saving some $$ a few years back things will b different today, she'll b able to get her things she wan as and when she wan.Anyway no use crying over spilled milk wat's pass had pass.Just forget it.Just start from now.

I don't know what she take me for, but I do take her very seriously though we're not legally married, I've already considered her to b like a wife to me. I tell her almost everything and discuss with her over most matters(say except those that I forgot or those that need a speedy resolution). To me she give me the feeling that she will only come to me when she has a problem. example the insurance case, I don't even know that she bought a policy until she have already subscriped to it for almost year. Then i only came to know abt it when she wanted to terminate. In other stuffs though she came to seek my advice and though after we've discuss and come to a agreement on the next action step, she'll not execute it. Why is that so? Is it bcos I am not working and inexperienced so my advices are mostly "rubbish"? or is it I am just simply taken for granted? I dunno...*sigh*

Breakdown of dd's pay and my calculations:
income:
Take home pay :$1880

fixed expenditures:
Car monthly instalments :$285
Home allowance(home Tax) :$500
Season parking (monthly) :$75
car insurance (monthly) :~$200

var expenditures:
Food :$100 ($5 every meal,a month ~20 working days $5x20=100)
Transport :$~50 ($2 everyday($0.83 a trip) + some unexpected trips)
Car petrol,parking :$50(conservative figure hopefully can meet)
coupons, cash card

thus she still should have $620 if my calculations are correct and she still have to spend on some hidden stuffs like facials, Amore membership, etc...

Well hope everything work out well...well just voicing out my tots no hard feelings...just feel better after voicing out my concerns...
Sorry DD okok?
