PLEASE HELP! This Lady Has Helped Me A Lot But All She Wants Is Marriage

Just saw this on a site about

a guy
and his girlfriend who has been helping him:
I met a girl after my service year in 2013, but
then she wasn't working, we met and started
dating. Two months to our relationship she got a
job and has being supporting me financially
because am still yet to get a job.
She rented an apartment for me and even
furnished it, she pays all my bills, including
feeding and clothing me. But all she wants in
return is to get married to me.
The thing is, we are age mates. I don't think it's
wife for me to marry a girl that's my age mate
just because she has been helping me... I'm
confused!
