Kevin,
listen to me my friend and whatever I say just follow it if you want peace.i am a girl 24 years old.your story is similar to me.i had a boyfriend,4 year relationship but all that broke because of his cruel family.
rather i would say because of him only.
whatever and whoever say if a guy loves you then he would fight for the love.
I am an Indian girl and my love for him was unconditional.he never cared for me as much as i did yet i thought he loved me truly.he left me for his parents.the cruel parents,i cant explain.they created a trauma during my examinations,not welcomed my father honourably and he,my so called love explained me that they were correct.

Kevin,i have more or less faced the same condition.if you truly want peace threw her out of your mind.
there was no one to help me out.its just been 5 months for my breakup but now i am fine completely.Do not consider that gal as your first love.follow the NO contact rule.you have to forget her and ask for forgiveness for you from God.I am not saying to treat her badly but you should threw her out of your heart and mind.the person who left you dont deserve you.
You are a peaceful soul who do not need her mercy.try to find a girl who loves you.you would not be fine at the very early stage but gradually.just look at her photo and see the negative qualities in her and then do not contact her family.
life is your,whatever you decide.but what i have done i told you.my ex now pleads infront of me but i dont give him a damn look.i tried to harm myself even and now i am not interested.if you want peace try my friend..
