While you message to your gf/bf
most probably you will be expressing your love, feelings toward them.
Some are good and some are not good in expressing.
That dosent matters.
What matters is how the receiver mean it.
How would you feel when you message your sweetheart telling how much you love
and in reply the sweet said its flirting..
How will you be feeling???
All i want to say is no matter what it is.
Dont take it as a flirt.
There are people whom they really mean it..
