Actually depends la...if the guy already has feelings for her,
and then he is the passive type who doesnt want to make the first
move, then the girl makes it instead, that wouldn't be so bad I
guess. Cos the interest is already there for both parties.
But if the guy initially doesn't feel anything for her and he got
together with her just because he wants to feel wanted or maybe
treating her as a substitute/spare tyre (who wouldn't want
something that is being offered to them continuously, free of
charge?), then yea, the girl might be the one suffering in the
r/s.
