well... for me, wat me and my gf usually do is that we sometimes split 50-50.. wat i mean is that, when we go out (dating), i usually pay for the food, and she pays for the movie, or something like... and sometimes, if im short of $$, she support me and if she is short of $$, i'll support her, if i have any $$ left. it all depends on how you work out with your partner.. but i dont know. thats how i do it.
