if is financially not stable that y u dun wan to marry her,
discuss with her about it. dont jz keep quiet. tell her your
prob... if already together for 5 years, she should roughly know
how much saving u have. if really not enuff money for a grand
wedding, can go for ROM reception, buffet dinner. i have many
friends, including my sister opt out for hotel dinner wedding. just
a small romantic lunch buffet will do the job.
but if u really dont intend to marry her at all, pls let her go. 5
years aint a short period for a gal.. dont waste her
youth...
