Very difficult to get over the breakup if ur boyfriend is possessive

Hi,
Im from India, recently I broke up with my boyfriend. we were in relationship for 2.5yrs.initially he was very nice,handsome,caring gentleman, but as we started dating n all I came to know that he is very manipulative,controlling,possessive person, he feels insecure hence he started keeping watch on me. he took all my facebook,gmail password by sharing his own passwords. as I was never interested in his account I dint check that..but he started checking all my facebook chats n even emails. then he started taking control over my mobile..he put so many application and started checking my mobile from his office,home etc. then base on that he started questioning me about that "why u sent this adult joke to this friend? why this friend called you darling ..he used to keep watch on me through my mobile application( if u put that application u can control your mobile through pchence you can even use camera)

Next part was that he started isolating me from my family & friends. he introduce himself to my parents n used to behave very nicely with my family.used to help my parents so he had very good impression amongst my parents n brother.bu then on the other side he cut out all boys from my friend list by saying that these boys are not "Sanskari" boys.then he moved towards my best friend I knew her from school days..but because of his own image about my friend he wanted me to stop talking to her..then he said from now onwards I will choose friends for you..i was like" what??????? why u`ll choose friends for me???" then he replied that for him im like his baby..so for my safety & for good sanskar he`ll do that
Then he started insulting my parents in front of me..then he started criticising my parents by saying that your parents don't need you they are just concerned about your brother ..so you have no value in your family...
Also he used to insult me by saying about my colour or saying that your becoming fat..hence I cannot take you to my parents and cannot ask about our marriage...then he used to criticise about my culture,values societywhich used to bother me much..
After all this mess I decided to broke up with him but after breakup also he is sending some blunder messages to me,to my dad & brother..he just want to disturb my life..n he want to make bad image of me amongst my family and friends..as he hacked my mobile he is having all my friends contact numbers..
Im feeling so sad though my parents gave me support at fullest...why he is doing all this things to me what he will get by controlling my life, threatening my life..one more time he tried to contact me by saying all emotional shitt..but I dint change my mind..coz I knew he`ll definitely repeat all those things again if I will fall for him

It looks like this one slipped below and no one commented here. Anyways, I hope you have not changed your mind. He is emotionally disturbed, it appears he had a complicated past or may be childhood.

He is just insecure and a guy with negative attitude towards life, actually he need psychological support but definitely you are not the one.

The day when he installed all those app in your phone, you should have understood that he has trust issue and you can't have healthy relationship with such guy. In the first place why you let him install all that shit in phone.. now you have the consequences. But your parents are with you, you don't worry about it. If he makes more menace, you can go to police after taking consent from your parents.
