Been through the same thing, honestly, it helped shape the person I am today. I refuse to let someone get the best of me.
I loved my ex so much, it was ridiculous. He would barely speak to me, this went on for over two years. (A lot of other things went wrong, but this was always what hurt me the most)
It makes me wish I could go back in time, just to leave him a lot earlier than I did. But I can’t, however I learned from it, and I won’t make the same mistake again! Hope the same thing goes for you (:
