If they aren’t ready or man does not know if she is the right one then why should he not let anyone else to make a move on her??
Yes.
This kind of long relationship is actually more ridiculous and should be taken as that both individuals are not sure about each other.
And they are open for anyone to grab any one of them.
No one has a right on other. No one should blame other or cry/complain other person, for being grabbed by a third person.
