how long is "after some time"??
anyway, as time passes, the feelings for each other will diminish.
Worse still, it can even be faster eroded due to disagreements and
quarels.
Maybe one should take a longer time to understand your target
before you make any move to be with the person or even going to bed
with him.
Maybe you should be glad that he dumps you sooner rather than later
only to find out he was with out not out of any love, but just
responsibility.
