relationship and money matters

its amazing and depressing how money matters can affect one's relationship

i heard a case today while travelling in the bus to work

conversation goes like this
2 gals talking to each other:

"i broke up with my bf a few months ago"
"why?"
"family against him cause he is not earning as much as my mum and also my eldest sis who is a high flier"
"how old is him? how much is he earning?"
"30 and earning 4K"
"i told him to change a new job and ask for higher pay and the recent one will be the third one"
"i asked him not to get the car to deprive himself of cash and he got pissed off"

i was thinking to myself
of course he will be pissed off

he is dating the daughter not the mum, the mum has her interests at heart but i think this is more than the mum should handle and meddle with.
the poor guy thus has to change job and has an "underground" relationship with the gal cause he has to "show his worth and paycheck" before approval from her mum
the guy has to live HIS LIFE too not just living according to what the gf wants aint it?
the gf after being stressed by the mum tries to control all his spending habits even though i THOUGHT its reasonable enough for someone who earns like 4K to support a car.

that's not how relationship should be.. isnt it?
so in the end a man's sincerity in marryin the gal lies with his paycheck and his financial support towards the gal?
even if its loveless? meaningless? no spontaneity? no laughter? no responsibility?
( i meant MAIN INDICATION of a man's sincerity)
i know love cannot bring bread to the table. but love SHOULD be the cement of all relationships. the rest can be worked out TOGETHER or compromised isnt it?

its complicating and no "fixed protocol" for such matters.

i am not saintly.
i am not as generous.
i am just making do with what i have.
Treasuring what else i have.
i cant apply "what others have" to myself
it depends on situation.
its always good to have more, what happens if there's not enough money?
DUmp the gf/bf? hop to a richer money tree?
ENVY will creep in and destroy yourself and the relationship.
there's no end to comparing.
if two ppl are fine with the arrangements they made between themselves, it'll be fine. aint it?
when u have the genuine support of someone, nothing is impossible.
