The problem is humans are directed by their goal. If the goal was to stay with you, it would be that way. But, if he wants to explore other options then it's his life. You can write your side of narrative on a positive note but after a reflection on how you get into a relationship so for that you can consult a thrapist

Seek counseling sessions to improve your perception and behaviour.

Hi..over a years either relationship becomes strong or you have to let it go if your wave length does not match..you cant burden yourself.

Hi,You may require professional help to deal with stress

Hi Let it go

Hi... This is unfortunate to witness how we have so unilaterally interpreted the western idea of dating without working upon the morality of it. So in Western countries people go out on dates to choose a partner for life or till the time love is alive. They are open to various kinds of sexual and social preferences but in no society you will find cheating and abuse acceptable. But in country like our's I see people using and abusing people and playing with their emotions with absolute disregard to human dignity. To summarize your query I would just say that, he was over you and didn't had the audacity to decently end a relationship before looking for another one, as if it was a job he wanted to switch for a better one. It's not about genders, it's about what we have become as a society.

Hi, This will have to be addressed in a counseling session and more details are required for therapy. So I'd suggest you to book a session on practo. And to answer your questions, this problem is deeper than who was wrong and what went wrong.
