SIS : Yes you are absolutely correct.

 Guys can act so immature sometimes.   Guys must understand that when gals parents start looking for a guy for their daughters its time for them to step up and ask her to get married with him. Failure to do so would lead to consequences like this.  If u loved her so much then why didn’t you get married all these years and made her wait all these 5 years. May be she got tired of waiting. May be she has her family pressure and she values her parents decision more then her own.  Its not easy for a girl either to leave someone whom she loved and start a new relation with someone she doesn’t know at all. It is much more frightening for her.  

IF you are ready to get married with her within the time frame given by her and her parents…  its still not too late… but if you just want her back in your life with no intension any serious relationship ( ie marriage) . I would suggest you to let her go… At least let her be true to her parents and her would be husband.  

PS: she might have loved you but sometimes a decision has to be made and she made her decision LOUD and CLEAR…
