Someone who was my firend asked me this question few days ago as a girl of mine was telling her love story with her bf.
We seat in silent at once.
It can be annoying when u sink ur heart into it. I mean love. It's simple and it also could be complicated when someone put some extra content in.
A film named "He is just not that into you" , at the begining of it, saying that we girls mostly like to persuade our friends by telling various kind of reasons why the boy or man didn't ring you up since u dated with him.
And the truth is , HE IS JUST NOT THAT INTO YOU.
Even ur bf, he will want to be separated sometimes. He will put his heart on another woman's eyes.
I got no answer to my friend's question.
But I think there's no point to seek out the answer. You'll got nothing but a quarrel with you bf.
Love is trust, though we trust too much when we shouldn't have.
