i understand ur dilema bro....
ur gf mom is trying to test u if u are capable to cough out that money or not...she dun care about the money actually...
but yea...someone needs to explain to her nicely that u hv plans for future with ur wife...and u must convince her u are financially okay to support both u n ur wife (n kids)


other bros in the forum dun suffer lk u do coz their parents are cool with it, or they are convinced their son in law are financially steady....

worse case scenario, u may hv to ask ur gf to 'borrow' u money so u can pay ur in laws 10k....but u will hv to keep it a secret from ur in laws...or they will never respect u till the end of time.
