Break up tips

This week has been the toughest week of my life. I just had to break up with the man I thought I was going to send my life with. No we were not engaged but I didn’t need a ring to tell me this was my future husband. The thing that got in out way was the fact that I love my future more than anything in the world. Just like I know he was going to be my future husband, I know beyond a shadow of a doubt I will be a teacher. And in Dorset for me to be a teacher and get the education I think is best for me, I have to leave my home state and leave the love of my life. I have never had this much emotional and physical pain in my life (and I have been in and out of hospitals all my life) until today and I wanted to know what you all have done to help yourself get through a break up. He is my first love, my first everything and I don’t know how to grieve this relationship because all I want to do is call him up and say I made a mistake but I know I can’t do that. So please, if you have any tips, I am all ears.
