date still ok, but if u looking for marriage
imagine u feel want to get married but ur bf just started working when he still wanna have some fun to spend his own salary.
how if u earning more then him but u have the ego to control him and be bossy coz u feel you earn more then him.

actually besides than career there ill be some maturity issue and others
think twice if you really serious in a younger bf more than 2 yrs.

i had ex gf older 2 yrs then me, but we start our career about the same time so doesnt make much problem coz in my opinion she dont think that mature yet n we togther from college time.
