I think we should all realise that guys and girls are different
species of people... they do and expect things differently...
Guys are more shui bian shui bian, and if their girlfriend treat
them a bit more shui bian, they also wouldn't mind. They can't keep
putting 100% of all his efforts solely on his girlfriend... they
have to allocate time for their family, their work, their friends
and their own personal enjoyment... Sad to say, men have much more
activity that he want to do alone than with their partners such as
playing games, going out with male friends, thinking of work etc. I
think that there is a need for realising that men will definitely
slip back in effort after some time. If one expect the other to
keep making effort in maintaining the relationship, you are
controlling him and really deriving him from happiness.
