hey there.
I thin you’re very heart broken right now because again, i keep seeing this in every person who is broken hearted and can’t get over it..
is:
1.you did not understand why and how she have become so cold, you guys were in love.
2.You never have an explain from her
3.No comfort from her, and you don’t understand how a person used to love you, going to be your fiancé can be so heartless.
4. You live and do everything for her, study for her and invest your time on her and do whatever you can to make her fall in love with you again.. you did way too much.
5. You have bee rejected by her many times so it makes you want to chase her more and more.
Please read this, you may can get some motivation and can relate to this man.

Im lost and completely hopeless after my brutal breakup.

She might have lied to you about if she have moved on. But find out once you’re ready, i mean words will come around.. Don’t look for it now as you’re not ready but just believe that she is moving on anyways. But if you can’t do that, the best way is to know and find out and face your fear. Once you know there is nothing left, you won’t come back.. This is what i can offer you right now.
I hope you’ll find your self in time.
What i wrote to that man, is also my words to you too 🙂
Please move on, you’re a good man and life have so much to offer and if you don’t let go of the old, the new beginning will never start.
peace and love <3
