How can i make it up to my x boyfriend after i hurt him with a lot of things i've done for us to get back ?

we always made mistakes, we are ordinary peoples, also we have the right to say sorry if your x bf if he really is into u he will forgive you. go and say sorry. tell him that u missed him a lot. do not afraid to say a lot wise people are saying it at this time. ask him a new beginning, which look like like first dating then really he will see u as his new forgetting the old. i did it many times too its so sweet when u meet back again.
