Who has romantic relations with a girl for some years suddenly declare that she is his sister?

It is quite possible and I have seen it happen!! especially if the boy's parents are forcing him to marry another girl then it can happen! Or if the boy has fallen in love with another girl then to get out of the previous relationship, he can do so!!

No I did not face this type of problem. I this this question is useless.

Till now it is not happened with me. Sorry i can't answer you

I do believe in the possibility of all things,its possible.

Anything can be possible. As lot of hurdles to cross for maintaining a relationship especially romantic.

May be, the boy finding reasons to break the relationship, under some pressure or something else. May be for the better future of both as well...Just to stay way. But I dont think it's the right way to end a relationship. True love should be treasured always as LOVE not as brother-sister relationship, though promises cant be kept throughout a lifetime. It's pure insult to that relationship if someone bring an end to the relationship in such a bad way.

 

It  depends on the person and not on the perception of an outsider...The girl might mistake friendly gestures to be romantic ...Because if one is romantically inclined and it is mutual, there is no question of calling someone sister unless they break up on friendly mutually agreed terms..

No. I did not come across with such cases as you mentioned. There was only one relationship with my wife, years ago. And that stayed.

 

Yes it can happen. At the young adult level it's easy to accomplish the boy girl friendship. As people mature and relationships and life take over, the rules of boy and girl also reflect differently. She might start dating some guy that sees you as a threat, she stops contact with you to please him and so on. Enjoy the innocence and meaningful relationship you have now just as you enjoy your youth. The world is better when we have true friends in our lives that bring us joy and meaning.or it can happen in the other way too. Even lovers do sometimes turning into brother sister relationship. i have seen many.

I have seen such case, but they have valued for their romantic relation and changed the sequence of relation and continued
