<human>: Can you provide a brief overview of the text?

We were together for 2 years.

So I came to Boston to be with someone I thought was the love of my life. She broke up with me citing her work as the reason. Yesterday I saw her making out with the coworker I keep seeing her with. They looked so intimate it didn't look like a fresh relationship. She left me for him and has been sleeping with him. Every day I have been mourning the end of our relationship, she has been super happy with someone else. I have never been so miserable. I want to be happy for her but it is impossible. Love turns to hate amazingly quickly.

I see them together on the main sidewalk often, it always makes me sick and I am having extreme anxiety about even going outside. I confronted her in text about it and said some very mean things. I burned the bridge I was so hurt by the sight of this. It is burned into my mind. I don't know how the hell to deal with this.
<bot>: My recent ex left me for someone else, I have yet to move on to even kiss another but she has been sleeping with some coworker she just met. I get to see them often and cant deal with it.
